Nice lighting of the product but the framing is a bit narrow. Also, the bottle should have been included in the composition. It's supposed to be an advertisement, after all. I'm not nuts about the bluish-green cast of the lighting on the background.
This seems a little underexposed.. When shotting still life in front of a white background you often need to compensate +.5 to +1 stop to get the white to come up a bit.. Godo focus and lighting though.
The colors in this photo are not very appealing. The green just illicits the wrong response. Great composition however, under sunlight this would have gotten an 8.
