It's really quite easy to create skins since no detail needs to be in the actual texture, just color...so you can just use flood fill and pretty much anyone can make a skin.

Example skin created by Arular -
It's very easy to add new skins to the game, I'm contemplating making it an actual feature...
Anyways, This has forced me to post some in-engine shots...you can see the work in progress on the terrain / dynamic grass system.
Arular made a pretty good skin...here is how it looks in-game...
What if you had to choose a gang specific skin @ the beginning of each round...ie: you first choose Black, Italian, Latino...then you choose a skin for your gang. This will allow user-created gangs to have original skins since they'll have to choose a gang type which will never change, and they could then create a custom skin for that gang, instead of having to create 2-3 skins for each body type.
hmmm....
