What can I say.. my favorite of the challenge because of the vibrancy of the colors. You probably got hit for not being entirely unique or original, but I loved it. Should have been higher.
The glasses are beautifully lit and very sharp and colorful. But the close, wrinkled background and the 3 and the ++ really detract. A plain white posterboard or piece of foamcore and no other elements would have made this good effort great, IMHO. :o)
The lighting on the glasses, and the play of the colors is great, worthy of a 10. The lighting on the background, with wrinkles, kind of kills the impact a little. This would be an easy 10 with a crisp, white background. Still a high score, though! Great work.
The three and the plus signs were not needed, they distract from the excellent colors and composition otherwise... 6.. minus the undeeded items...I would have voted an 8
