Nice, but the face could use more definition. Right now, it looks unfinished. Use a smaller brush and do touch ups until it looks perfect. Right now, it looks like you have the basic colors down, and you jsut need to refine the peice. You still have some work to do, but it's getting there :) EDIT- I jsut counted your colors, and came up with 229, not counting the text. That is alot for any peice. I would try cutting it down to at least 100, if not less. It can be done, all you need to do is remove colors that are almost the same, especially on the skin, I see alot of tones that are basically the same, get rid of those, nand maybe dither where needed to make up for those tones. You dont need as many tones on the guitar either. Or the clothes..jsut go through and eliminate tones.
