The reason you don't like them is because the render doesn't blend well. I haven't done much anime, but I'm working with the colors. If you look at them as abstract they don't look like a piece of shyt someone threw together. At least know what your talking about before you CnC please.
I can see your concept, it's really great. But when your doing a vector like this don't outline like this. Maybe add a little more scenery. Effects are nice.
