I think its too busy but i don't have as much to say as others here it just looks too busy to me. Maybe try a closer up picture of the dog for a better affect.
Does he have one blue eye!!!??? Cool eyes anyway!!! ...A close up of his beautiful face might be nice??
I kind of agree with the others, the pooch is lovely, but not clear. At least his face should be. The picture is a bit busy....maybe even if that gate (?) in front wasn't there...and maybe crop a bit off the bottom??
Not a bad shot, but I think it could be great!!! Nice job!
