This has the makings of a good shot, but since this was an advanced challenge, cloning out the jeans in the background and that white spot on the back of the chair/couch would've helped a lot.
bit of a snapshotty feel to this pic (but then you can't stage a shot like this), caused by the flash which has cast a shadow under the dogs, and the person's legs in the background. However I love the dog's expressions and it's nice and sharp.
I love how the models look so natural in this one! ;o) Such a spur of the moment shot it is difficult to suggest realistic improvements but a little more light on the left would have been nice.
