this one was kinda easy, its a straight on shot of maryjane taking off her shirt. speaking of which, her arms and hands were pretty tuff to draw (again using no ref as i was at a con, and drew it in my hotel room) i had to stop, sit back, and figure out which wrist went over what hand/arm, and so forth.
Eric, You are a excellent artist your proportions are perfect. If I were to attempt to draw people in any way they come out looking like a cross between jabba the hut and the blob. Excellent work can't wait to see some of your new pieces.
