SO far the advice is as follows:
Image 1: LOVE the style, break up the shapes a teensy bit more (paws? fur?)
Image 2: Back to the drawing board. The concept isn't bad but I was trying to bite off too much. Revisit thumbnailing, try to reinterpret.
Image 3: Dutch the camera the other way, put Mowgli into perspective, give his body a bit of twist/force. Flatted the shapes more- bring it into the same style as Image 1. Make the wall behind Mowgli Black, and invert his shadow.
Back to work!! =)
