The more times I look at this shot, the more I like it. I agree with some of the other comments about a more appealing background, but I personally like the crop/angle. ..Just browsing.. =)
I like the border, the colors and the idea you had. I just think that you missed a little bit at the perspective and the crop, if you have showned all the sandals from above with a nice background you would have a great image!
I'm sorry if i was rude, good luck to you.
This shot is decent. I like how the shoes are laid out and the different colors in the shot but it seems like you could've done a bit more such as even placing the shoes on some really green grass would've added a lot to the shot. I don't mean to sound harsh, I'm just trying to help by providing my two cents and you can take it or leave it.
