bentleya, i see you're going for the studio lighting setup. When i saw your shots, it instantly reminded me of this tutorial

http://www.cgarena.com/freestuff/tut...tudiolighting/

maybe do a search on google for 'studio lighting tutorials' or look for tutorials from other applications like 'vray'

Could be useful.

This is an excellent lighting tutorial. I'm glad I managed to dig it out.

These are quite old but maybe useful as well.
