Lacking in dept and the snout is too narrow.
Also, the mapping of the ears looks weird.
It's a nice idea and a good concept piece to go off of, but your execution
is a little.. off..
Also, looks like you tried to draw the neck on the head..
Yeah, don't do that.. Of course you can lead into the neck a bit by slightly
indicating it, but drawing the entire neck is bad.. Save that for your neck texture.
