Brilliantly done. The only problem I see is the bottom jaw, but since it's your first proper drawing and the rest of it looks so fantastic, it's not that big of a deal. The fur looks so fluffy and the paws are absolutely adorable. The extra fluff on the neck and the ears are ultra fluffy and really make the whole wolfie look good. There's wonderful color, wonderful shading and the proportions are amazing. The back legs are a tad skinny, but it still looks so nice! The front leg is a funky shape, but don't let that stop you! Keep it a tad more straight, like the other front leg, in the back. You already know how to do it because you did it with the behind front leg. The picture as a whole looks wonderful. I'm just nit-picky about specific parts. Wonderful job, friend!
