Happy belated birthday blanq!!! I hope you had a great day :)
I love this study, the fabric looks so real: http://www.conceptart.org/forums/att...1&d=1163332665
You're getting there with some of the figures, but remember to watch the proportions! I'm pretty sure the fifth guy (counting from the left) on the top of the last image is on steroids :P
Arms and elbows in the first image look really nice.
Keep it up!
