I'm still hung up on that art block I mentioned before :') And, for whatever reason, I'm struggling over canines to no end. So, no, the redlines aren't gonna be the best quality - sorry!

Overall, this piece is stunning. You are able to deliver the feel of the scene with vividness and detail, which is indicative of creative, talented artist. Everything, from the color choice, the breath, the pose, works in perfect harmony. Anyone can sketch out a character and color it in, but I have found that it's far more difficult to really tie everything together in a well executed manner. Well done.

Hower, in terms of anatomy, there could be some improvements here and there! I'll do my best to outline some general critiques to help you be the best you can be ^^

Starting with the pose: I think you choose the best pose you could have, and it looks great! However, it is a bit unnatural. I don't think a wolf can raise its leg quite so high, although I could be wrong. And if a canine could, the leg position itself would simply be unrealistic to any normal movement or gait.

I'll start with the front and move to the back. So, the head: I can see the perspective you drew in, which looks nice! However, to complete that sort of 3/4 view, the head can't look flat (side view). Extend it a little further to the right of the canvas, and maybe add a barely visible part of the left eye in as well. The right eye should be a bit higher up, seeing as the bridge of the muzzle meets the head farther back than the eye which isn't anatomically correct. The lower jaw should be wider, and have the same span as the upper part of the mouth. The, once you inclined the tilt of the chin back, towards the left side of the canvas, it should look perfect!

The ear itself is excellent! I would make it smaller, and move it higher up on the head, though. I love the accessories you drew in ^^

The neck should be longer and have less of a dip from the base top of the neck to the center/front top of the neck. Confusing, I know :') I especially like your work with the fur! It looks really smooth and well done.

Legs! So, the right foreleg, as stated before, isn't in the most natural of positions. Hey, the character is mythical, of course, so the fluidity and naturalness of the pose is up to you. Regardless, there is a little too much curve in the leg. The two bones (upper leg, which is far longer, and lower leg which is far shorter than the upper) are straight, bending only at the joint.

And then the back should meet the shoulders higher up, and the belly should meet the chest lower down. Other than that? I think it looks great! As stated previously, the piece in its entirety is gorgeous ^^
