Just something I have been working on to help me with lighting and glass effects. I would use YafRay but it crashes Blender :-? .
Looks good, but I would try increasing the lighting a little bit.
Wow nice work, i’m doing something similar and i’m just starting to use the texturing in blender, so can you tell me how did you do the reverse mirror effect on the top of the pawn it’s really well done and the only thing to improve is to put more light!
