This is a kind of fun little three-way collab thing I picked up from deviantart. How it works is, each artist draws a sketch, then you trade with someone else who does the lineart, then switch again and have someone ELSE colour the finished piece.
So, for example, I did the first sketch, then the middle lineart, and the bottom colouring. It's a load of fun and the results can be interesting.
it's really fuggin big so you might wanna open it in a new window to appreciate the RICH DETEL.
Or not. I don't know how you roll.
