The main thing people look for in a character set is versatility. It's getting harder and harder to make a good character set for V3 and make it a top selling product. In truth, the skin/character market, especially in reguards to V3, is becoming a very saturated market, and you're going to have to do a LOT to make your character set stand out. Although, I must admit, it looks very good :) The majority of the people here are going to be looking for options. Skin tones, make-up options, tattoos, poses, light sets, MAT poses, P5 material settings, morphs....AND all at a cheap price. That's why I personally stay away from character sets. Too much work for me - that and I'm terrible at texturing ^_^
