omg, the unwrap looks horrible. it is clear that your skin is very undefinated, you did completly useless micro details, all you need to do is to make every definated and clear. Now omg, i dont know what you did to make so much fuziness globally everywhere, but you gotta fix that, every blizzard skins to my knowledges are far from being fuzzy, they're clear and recognizable, along with the original faceless one. the purple parts are very blurry, make some muscles perhaps. stop doing these black contours around the shapes you make, its absolutly unnescesary to wrap your 100% black lines around a shape, that looks cartoonish to the extreme.
sorry but that skin isn't very good, nothing personnal, it's overrated by newbs..
