id have liked to see the glass a litle more to the side and a little closer so the straw wasnt cut off. and i like that the tire's there, but i can barely see it.
The green in this image brings out a lot of the interesting details of it. It has something missing to it though, I'm not quite sure what, but perhaps the trees in the background could have a little more detail to it. Nice try though.
This would have been more impactish with a less dominating background. I find that the heavy silouettes of the trees pull the eye away from the central glass. The dappled light on the table has an interesting effect.
