Interesting eyes, but the focus is off and that really drags this down - focus should almost always be on the eyes if eyes are visible, unless something else is being presented as the subject of the photo.
This is one of those rare occasions where the eyes should not be in sharp focus, it works really well like this it makes him look well spooky but I'm sure he's a great and well loved companion.
Interesting capture. As a photograph it is terrible........as an artistic piece it is brilliant. For now it is a 7, may go up on my 2nd pass thru. I bet this would look amazing printed large on metal.
