Hi there! I though, overall, this was actually fairly good at first, even before the redline! Here are some small (but detailed) pointers on drawing dogs and wolves:
The main problem here was the back legs, which were too stiff, and needed to be elongated, and the head, which was a tad too big, unless you were going for the cartoonism effect. The tail also needed to be a bit bigger, and the feet flatter because they are being stood on, and the weight of the body is pressing them down.
One way to get a good head start on drawing a sketch is to draw the basic body shapes in ovals, like i showed here. There is one main body cirlce which is pretty much round, depending on the position that the wolf is in, and then two ovals for shoulders and back thighs beside it, where the legs are attached. Above the front shoulder blade is a little bump sticking up where its arm moves back and forth. The tail is just relative, and can really be anywhere from as short as the main body circle, to as long as the whole wolfs body, not including the neck. Speaking of the neck... since the wolf (or dog, im just calling it a wolf) has a scruff on its neck to keep warm, and just because of its dense chest fur, the chest has to be puffed out a little more, to make it seem fuzzier.
Around the outside of the actual redline, I drew some pointers on other body angles/parts. On the bottom left is a closeup of the eye, which you can't really see on here very well, but for future reference, the (realistic) wolf eye is more in the shape of an egg than a harsh-lined shape. It can change from where the wolf is looking; for example, if the wolf is looking up, the eye will come to more of a point on the top, and get bigger. if it's looking to the side, it will come the a point the opposite side it is looking towards. (confusing, right?)
Next to that is the front body shot, which isnt very important. I was just trying to show the relative size of the ears to the head, and the leg length to the body height. Above that is the side head shot, which shows the position of the eye, and length of the nose relative to its head. I didn't make the head have a lower lip jutting out underneath the top of the jaw, but there is one xD (sorry bout that!) The eye is actually pretty small compared to the rest of the wolf, and so is the nose, which sticks out a tiny bit from the mouth. The ears are a little bigger as well, which isnt as important, since the ear size of dogs and wolves can actually vary quite a bit, especially in dogs.
I also wrote some tips in (as you can probably tell xD) and I apologize for my awful handwriting; it's hard to write with a mousepad! Some of them include bending the back down a bit, because in your lineart the back is a straight line across, whereas it usually slopes down towards the haunches. Also, the nose is bent down, and then goes up again at the nose, creating some depth to the realism of the face. The body was a bit long, so I shortened it, and the feet have to be flatter.
Anyways, I will stop my incessant rambling, so you can stop reading it xD
Hope this helped a bit! <3, neonkiwi
