Jackson Kelly rendered in LuxRender

This entire project was done in about 10 hours, including rendering time. About 5 hours spent modeling, another hour trying to get materials and UVs right, and the other 4 hours were spent rendering it inside LuxRender. I’d like to know any improvements I can make. I’m fairly new to Blender. Oh, and I used a LOT of floating geometry.
Anyway, cheers.
