This is a fully blown-up image of my avatar. I hope you like it…

I will add improvements, but probably not textures. Comments? I would like to know.

Your character isn’t very good detailed…but if it’s just for a 65*65 avatar, it’s not important. Your thunders are too regular (the twice are the same, exactly…)
It’s an avatar, so the important is that it pleases you !! :wink:

Some suggestions:

Tweak the Spec and Hard value to get a more realistic skin
Increase the subsurf amount to smooth the mesh
Maybe tweak the lighting
