Hmm, pretty good image, but it does lack some "umph." I think that the biggest problem is the lack of contrast(a little too much opinion, I know), and that big white splotch. It also looks a little better turned sideways, but that's my opinion, again. The composition is good, the lighting is pretty good. just needs a little more. I edited your image a little, although I messed up some parts. Just a little of what I thought could help.
The picture is not of a Coke can. It is of a thermometer that is outside and weathered from the sun. Thanks for your comments. I was just trying to take a close up picture of it. May not be the best though. But I do appreciate the comment
Hi Anne Interesting composition, buct lacks overall appeal. I think focus or intention is not there. Say if its coke then red is not there., if its perspective then its not really there.It could have been more interesting if it would have been taken in landscape. Anyway these are just suggestions, i might not have percieved the interntion correctly.
