I am digging this style so much! As someone else mentioned, if you want to go a little further you can add in some edge highlights for wood cracks and such to get those nice edges pop ( you done that on the asset with the blue pants logo which makes those details really pop).
This is what I started on roughly a month ago, I was caught up in something else and recently started to work on it again, but I turned the angel into a centaur. :)
I'm an animator/rigger interested in making characters for unreal tournament, anyone else interested in collaborating? here's a link to my reel - http://www.smootharcs.com/reel.htm
