awesome turn out! I like the cool balance on the alien suit.

Looking great, love the super long hair.

Hi Malcom!
First of all, you are doing such a great job so far! Seeing you put this amount of effort into it really motivates me to use my every spare minute to work on it myself even though I have hard times with finding them ^^
I personally like the last concept sheet the most + armor design from number 7 of the previous sheet. Would love to see that combined with number 2 of the last sheet. The first sheet has some nice ideas as well, which of I would consider the ability to fly the most attractive. It seems that she lost that in further designs and I kinda feel it's a pitty maybe adding a little backpack providing that kind of ability could be cool, but that's up to you ofc

Anyway I am looking forward to your illustration ideas mate! Have a Happy New Year

So as far as all the designs go they are looking pretty rad, but imo i feel like the newer character sheet offers way to many designs that it honestly feels like multiple character in one sheet and loses the feel of one character all together. So what i would suggest is that in your next post you should take a break from the designs and stick to one and fix it up at you go along.
And to answer your question (honest opinion):
1. The early Concepts do, the newer ones not so much
2. The early designs seem like they would be fighting huge mech's or aliens, the newer designs seem like they do recon and assassinations missions (which could be epic in its own right :D)
3. Very sci-fi
4. I do see these character very much fun to play in a game but it looks like the character mood kinda changes as the concepts go down

Also if i had to pick as design:
B or K
O
And 3
Hope this feedback helps, hope to see the finished sheet as great as you wanted to be and cant wait for the illustration

Yess another sci-fi comrade! I've been mulling over this post for a bit, there's quite a lot to consider and several designs that I like quite a lot.

So my thoughts:

Overall all characters have a sci-fi vibe (you had no problem there!). Characters that I feel are badass, fit sleek/agile/quick, and can picture them being epic in some way:

First sheet: D, J

Newer sheet (1-5) I feel definitely encompass sleek/agile/quick. For me personally, these have the most visual interest because of the combo of colours/materials/etc.
The badassery will likely have to come from how you illustrate her. Of those I prefer 2 and 3 because the chest/abdomen armor makes her look a little more badass.

I feel that the overwhelming majority of these characters would be fun to play in a game/see in a film.

I also really like the idea of bug inspired mechs, I don't have a definitive preference between 3 or 4, they both the the potential to be super awesome.

Looking forward to seeing more!

Nice, very cool idea. You are missing some stuff, right now the costumes, the theme doesn't feel very solid. Something to define this character, maybe shapes, tech.

You need to find a balance if her purpose is to heal and provide support or just do massive dps but little healing. If she is a pilot, look at some real world references of a pilot, the equipment, the gadgets, what do pilot carry with them. If she is quick, sleek look at references of athletes that wear sleek, tight clothing( like those winter Olympian speed skaters).

Her mech is also missing a coherent theme with her. Sometimes too massive of a object can overshadow something. Study a bit, learn at how things work in real life. There is no black or white answers, all of the above are pretty grey, but these are just my personal preference and suggestions.

I didn't mean it as rude, but it seems like you're recycling some of Marc's design language in your own drawings. I really want you to think critically about the design; really give her a function. Sometimes simplicity is better, ya know? Don't get too caught up in the details.

I know it can be kind of intimidating to see so many artists pouring a lot of detail into their work, but its also not a bad move to try to go for something simple and Immediately recognizable as well. Like @mdaven_art Explained, its easy to get caught up in details.

give some examples of characters you feel aren't forgettable and predictable

What helps me to try to think of a "Memorable" character is to think of a pretend franchise for them to exist in. I think, "Is this a character for children, teens, or adults?"
Consider:
A character intended for children should be easy to draw, and remember. They're cute and empathetic. (Example: the Character cast of steven universe. And even more memorable, Pikachu.)
A character made for teenagers should be relateable, more realistic but not jam-packed with details. They should also be teens themselves. (Avatar, Teen Titans, and most anime)
A character made for adults can be really hard to nail down in a few words, but they usually aren't afraid to be ugly. Most adult cartoons have really ugly characters, but that's a key thing to consider. You can remember an ugly face because they have unique features. (I hate to drag them like this, but Roadhog and Junkrat are pretty ugly but they are memorable. their ugliness is part of why a lot of people love them)

Lastly, find a theme to draw your character with. An example of a character with a theme would be Yugi from Yu-gi-oh. He's composed of primary colors, sharp angles, and Ancient Egyptian aesthetics. Its so hard to Forget yugi because of his hair! He's Iconic.

Sorry I went on a big 'ol speech, but I feel like this advice might help gain a better understanding of what a "memorable" character is.
TLDR:
Make up a "Target audience"
Pick a few themes you like, think of a character based on the themes
Create that character with the intention that someone can describe them without actually naming that character. If someone likes your character, but doesn't know their name, they can go to google and type in "Bald kid with blue arrow on his head "

Anyway, i've had like, 0 sleep so if this is all in a foreign language I apologize.

Hope this helps!

I can really see the Miyazaki strongly influencing your characters
Great work! Like the design themes alot <3

Damn this is active and i don't think i've even seen this thread, how'd that happen.

I like the progress you seem to have a handle on this, i like the wrist shielding.

Can't offer anything but praise and support, continue it's looking like a great contender.
