I personally would make the shadow on the wall smoother and remember that the other arm has shadow to- otherwise it come out kinda "cutted out". Stump for that matter is still brilliant. Every time I see him i feel like cuddling him
I see what you are talking about with the "cut out" effect. I think it might be best to work the shadows out on paper instead of trying to create them entirely in Photoshop, especially when they are so unusual or extreme.
Anyways, thanks for the feedback, it's much appreciated. I'm still experimenting and learning about this whole Photoshop coloring thing, so any comments I can get are very helpful.
