I think it's more than ok, it's amazing!
I do have a comment on the muzzle though as it did force itself in my eyes. It looks like it's twisted. Because of the way you did the top of the head, the muzzle is in the wrong place.
In your next one like this you could move the left nostril out of view almost (just show the raise where it would be, so as if your moving it left)
The right one would need to come up and left more.
But otherwise amazing. Well done!
P.S Can you have a look at mine, I'm talking about the 2 in my sig
Edit.
Cancel the above I've just seen the ref!
I myself would have had to change it though and done what i said above.
How do you personally work with the layers?
