actually, i shun layering like the devil. the only time i use it is in a picture with lineart... and that would be 2 layers... or in a picture with lots of lighting effects. i think this came out pretty good, but you could have cleaned up the outline a little more. i like the 'messy' smudge effects on the skin, and the indefinite light source. people say you need an obvious light source, but they are wrong!! :D
