the left side of his body(his left) is looking... weird. His hand looks like it was cut off, turned 90 degrees, and reattached. The part you intended to be the webbing between his thumb and forefinger in fact looks like his palm, and his thumb goes out at a right angle, and bends straight under, a feat which I am sure no one is capable of using only one hand. Also his kneedcap is extraordinarily small, and his other one is big in comparison. If you were trying to give the illusion of distance, his legs must be about 30 ft apart. Lastly on his right side, the muscles in his forearm run all the way up through his bicep. In human anatomy, they are anchored just above the elbow.
