get rid of the gradient on the text, its too subtle and looks kind of like a computer error. I think that you should make the yellow on the right dog a little darker just for some variation. Also, I think you should move the caption and make it its own separate block of text.
At first I thought the dogs were kangaroos. If at all possible, I think thinning them out in the shoulders or stomach to help with the perspective would help establish their dogness. No, that isn't a word.
I think this looks nice. I think if you make some more variation in the red on the dogs it might help to emphasize the forshortening.
the perspective, coloring, and text use fuckin ROCKS!
