Character Design - My first Character LineUp

This was a school project which I hadn't so much time for unfortunately, but it was fun.
I thought of a story based 2D Game with fighting features, cool wrestling moves, streetfights with knifes and stuff. The mood should be kinda dark and shady, but it should not be seen from the outside, but from the storyline and the acting. From the outside it should look colorful and happy and the inside and backstories of the character should be dark and fucked up.

It is now 2 weeks ago, that I "finished" this project, but now I already see the mistakes, so I have looooong way to go, until I'll be able to do the really good projects. But it was fun, and I learned a lot and I have to keep going.
