I am not going to comment on color, exposure etc because I am looking at this image on my old cruddy laptop.
It appears that the focus is not crystal sharp here, but I think that works well. We see enough of the detail, and it sort of fits in with a shaggy dog
Perhaps the only thing I would do here is to crop the left side just a bit to put his head a bit more off center and give the feeling of even more room on our right.
All in all, a very good shot.
