Hmm. Do you mean it's too blocky or the texture itself is something you don't like?
Both issues are likely to be attributed to the very low polygon count.
If normap mapping would work on my laptop I'd have a bash at adding more detail that way via zbrush, since that's the method the industry uses. I'd have to UV map the meshes properly though, which would alter the original texture.
I'll add it to the list of things to do once my troll project is done =]
Speaking of which, here's an update on that one =P

I'm currently working on the texture, which I'll have some pics of soon n_n
