Short answer:
No
Long:
That would be considered a fan-art which is prohibited from what i see being posted in response to similar questions.
@shalva Talent falls under your concerns, it takes talent to use good judgement on topology and layouts.
Seems it can be either, since there is no limit you might be able to do whatever from what it sounds like.
For everyone coming by wondering anything this is the "rules" section, you click that img in the first post it takes you here:
Can i start with a base mesh?
@saycats you can enter both 2D and 3D category, but the entries cannot share anything - concept, design etc, it has to be completely different for both entries.
@aesthetic :(( you can enter and share your work, but you are not able to win any prices. If you want, you can still join just for the motivation that contests and deadlines will give you. I'm really sorry the laws in Quebec are so bad.
@fonx32 no, we want to see your original designs and ideas! 
@zyp hey, thanks for taking the time to answer people's questions! I re-answered some of them just do they know what's the "official" stance, but I really do appreciate your help!
We'll get back to you with an answer about the base human design (and the one about base mesh) as soon as possible.
We want everything in your entry to be yours. Everything on the concept sheet has to be made by you, including the sketches, silhouettes, design etc. from which you modeled.
You are free to use your own basemesh, but not somebody else's.
I hope that clears your questions, if not, feel free to ask further!
Also could you clarify if its alright to use "make human software" to create a base mesh?
What about the use of user created alphas and brushes (not made by me) in zbrush and photoshop if they are sufficiently modified in the final model?
You can only enter with work that is 100% made by yourself. 
Understood, though I've noticed a lot of submissions are using make human for their base models.
Also while zbrush comes with its stock set of brushes and alphas, there are hundreds of alphas used that are unofficial.
In anycase thanks for clarifying.

I was curious what will fit in a marmoset (mview) file of 20 mb size. So I did a quick test. My old character 100k triangles with 4 shaders applied. Every shader with a 2k sheet of normal, albedo, metalness and roughnes textures.
Cheers
What Rath said and it is a pitty showing progress shots should be mandatory, i realize this eliminates a few current in the works items, but fair is fair this is more about learning and community interaction, (i'd like to believe anyway) than prizes.
But it's your rodeo hosts.
@rath-nikhil @zyp hmm, let me just say this - the works will be judged by professionals who will be able to see the progress shots (showing progress shots is mandatory). I have absolutely no doubt they will easily recognize what is original work and what isn't and they will disqualify any entry that they'll judge is not up to the standards.
And just throwing it out here for others, for some guidelines about the 3D entries, the FAQ might be helpful.
Thanks for looking into that. Should certainly save some time when trying to dial the scenes in for that current limit. Much appreciated!
This will be fun!
Just for anyone wondering if you can do a good job with cloning, as in using the see through in zbrush and replicate a silhouette on our base mesh then use retopology you can still do what you want though at least you have had to have done the strokes to get to that stage.
Just in case the harsh / strict rules deter anyone, you just have to put in the work like others.
Hope to see more updates to those that fall into the category of disqualifications and make an effort to change this.
I didn't mean to press that it is for your benefit that you learn to make things more appealing than to just use a tool that creates an appealing base like make human, that is really a hinder to progression in your artistic endeavors than anything else.
It is really a good thing in disguise i have to learn this also, so you are not alone.
Thread deleted and i have to start a new, so i am not blowing smoke up your butt, I will be doing the same and showing the progression as well to solidify my position in this race.
Best of luck to all those whom have to do the same.
Just to be clear, I've deleted that topic as a request. You weren't disqualified 
Is the T-pose mandatory? or can the character be posed? i see alot of entrys were the models is sculpted already posed
Buen día quisiera saber donde potear el bosqueo y el arte final

Hey, I have a questioned regarding 3D character rules.
I am aware this is a solo contest but are you allowed to have your character rigged and animated by someone else? For example doing the final pose and maybe some animation stuff in the marmoset viewer?
Does anyone know whether this is ok?
Thanks!
I wouldn't do it, i think the theme is do it all yourself, from what I've read.
@FemCharles It's a solo contest, one entry by one person only.
