Hey, Mar! Thanks for your comment. 
I do really recommend that you try out 3D softwares, Zbrush especially! It has helped me think about shapes and lighting! You spend a lot of time problemsolving if the concept for the model you are making isn't clear, and you often have to do it in ways that fit reality. This mentality translates over to 2D, and is really helpful!

Hey all! I made a scene for that sea creature I made a few days ago. Hope you like it!
Love the end Result. The expression gives her a lot of character .If i may ask, did you use grandient maps to color it?
Hey, Fira! Yes, to both questions! Zbrush is an awesome program
And as for the painting, the technique I used didn't necessarily require gradient maps, but it is a quick way to put down color so you can work on top of it afterwards! By managing values separately, you can put more focus into making it look right and then jump into colors with gradient maps and start working off there Glad you liked my derpy fish too!
Nice blog! I can see you grew a lot every day!
The last scene with sea creature is very very cool I also like your sketching style.
I think your 2D digital painting/rendering can use some work.
Some pics of what I've been working on lately! Going to texture this soon 
Nice sketches!
About Symmetra: the anatomy of her upper body is off. Try to build up the body from basic shapes. I did a paintover:
Thanks for pointing out the anatomy in your paint over! This is really helpful.
I'm glad! Keep it up ^_^
Here is the textured model that I posted a few days ago
A wow, I'm really loving your 3d work, especially your Zsketches. Incredibly inspirational stuff, here. The form in your earlier demon-esque heads is just great, man. Keep it up!
your 3d stuff is great!, I really recommend you to study after Hampton or Loomis, this help me lots drawing the human figure, if you need some tips or guidance let me know!, I'm no expert by any means but maybe I can help out.
@delta_hexagon @Schmigel and @Imphelikz - Thank you!
Not sure who you mean by Hampton, but I love Andrew Loomis, he was a great artist from the early 1900s. I am probably going to look more into references from this time, as there are a lot of great forgotten modern artists from it. This will have to wait until next week though!
Wont be posting until tuesday as I have an exam on monday Thank you all again.
I'm finally back with another model! 
Nice work!
I think I would make both the chars eyes much smaller/not that wide open. It looks like they're VERY scared or excited 
With the right one, the jaw line stops too far to the back and her ear is quite thin. Her nose is very small for how realistic you've drawn and you give the chin too little space. Here's what I mean: 
I think it helps to first sketch out the head shape and proportions before adding any detail.
Hello! Thanks for the paintover. Now I see what seemed so weird about her!
I do indeed sketch out before going with details. Though one of my priorities are always to overexaggerate and alter what seems weird after.
.Did you sculpt it in Zbrush?
