personally I liked it before, just if the front triangle plate was bigger and wasn't floating.
Bump maps are out now everyone!
So I think it's time to do some experimenting with them!
A few tips, make your head as normal, but make a new layer, then do all your shading on that.
Disable the shading layers and save as head. Then enable the sharing layers and disable the regular layers and save as head_bumpmap. Profit.
