This is a great start. It’s starting to take shape already. I’m not going to give any crits this early in the game, though. But from what I can see, it’ll turn out fine.
just dive in, ears are never, never, easy. unless it’s a toon. also this dog seems to have slightly too much arch to his back, I am guessing he was in a strange pose when photographed, so I’d straighten him out a tad.
