Very nice photo, the lighting and composition work very well IMO and the almost classic green or aqua colour just seems to ad that little extra something to the scene.
I love the simplicity of this shot. The off center composition is very nice. The amount of texture in the glass you were able to maintain is very, very good. I have a bunch of these and toyed with the idea...glad i didn't - this surpasses anything I could have done. The lighting is excellent - really lets the shape and texture stand for itself. Also lets the color be itself and not forced at all. Very well done - underappreciated in the voting I think. Black background was the only way to go as well...really lets the insulator stand strong and bold. Nice job Roxanne!
