Yep, David's help made it improve greatly, regarding shape and color choices, specially contrast wise, which was the biggest problem in your initial version (that, and the brightness was too low).
The left leg looks longer than the right one, i'd make the pants extend a pixel down, stealing a pixel from his shoe, and remove the space between his legs that's making the left leg look slimmer. Maybe add a bit more saturation on the skin, not too much, just a tad more orange, and a bit more contrast to the head.
Welcome, and keep'em coming!
