Beautiful! I love that you did each individual scale and I know that definitely took a while ^_^
My only crit would be that the ventral fins aren't as clear as the anal fin ray's are, I see you used a blur tool but it would be great to have a little better definition in the ray's of the ventral fins.
Other than that he's beautiful! I love just the simple white background, really makes him pop. And of course his face is the cutest thing ever lol, them lips!!
