I have few questions also :
1) Are your textures under licence ? and wich one ? (creative common ? commercial use?)
2) most of your textures are photographies, but it seems your are compositing some (sci-fi section), right ? I think the best is to provide it the more "neutral possible" on colors, especially blue/green teinted pics. I'm interested in some of your picks, but some are over contrasted/satured.
I'll a look on other stuffs of your website later.
