Shinto Shotgun

I’m working on a Shotgun with a sort of far eastern theme to it. I’ve gotten fairly far on it but I think it lacks visual interest and I’m not entirely sure if the tassel portion looks quite right. I’d appreciate any tips in general for improving on it.

Credit to cgcookie for help with the shader which is based off their car shader tutorial. I’m going for a good render mainly on this one.

Looks like a rail-gun.
