Good composition. Technically this photo has room for improvement, though. There is a lot of blown out white areas with no detail. The harsh mid-day shadows are also pretty aweful.
the brightness in the picture is uneven to the point of being annoying. Certain portions (top) are overexposed and at bottom it is clearly very dark. There is no
clear focus on either foreground or background. If the glass would have been in clear focus the sharpness around the stem and the clarity of water smoothly overflowing could have given a very nice impression. It appears that the glass has alot of smudge marks .. that is distracting too.
I can't see the product label clearly. I don't understand the choice to crop the bottom of the glass. This is not a great liquid shot. The water looks murky and unappetizing. This is quite overexposed. The blown-out bottle almost disappears into the blown-out sky.
Could be worse, but it just looks like a point and shoot photo- there's way too much overexposure, and it just appears somewhat takcy in quality. The composition's nice, but it's just lacking a little bit.
The idea is good but unfortenatly it is to over exposed.. There is not much details left of the botle and the sky. My guess is that your camera was fooled by the green and dark foilage in the background. The camera though it was much darker and the shot got overexposed. To solve this kind of problems you can try and expose at something on aproximatly the same distance, with more natrual light. Lookthat expsure and turn the camera against your composition.
