Here you go, I have redlined your wolf. c:
I understand this is incredibly messy and confusing to look at, so let me try to explain all of my messy scribbliness to you.

I'll start with the ears. Here's a sort of reference photo for the ears. Their ears end behind the cheek-fluff, not at the cheek fluff. I made the redline a bit lower than it should be, but what I was trying to express was that the ear should be a bit lower.
I'll start with my little eyebrow things. There's the little hook-thing above the eye, and I sketched in what could be considered an eyebrow, which I drew as an extension to the hook. Looking back, I'm beginning to think you weren't drawing the hook above the wolf's eye. Some people do, some don't. It's not anatomically correct or incorrect, just something some people decide to draw. If one does draw the hook-like curves, though, in 3/4 view like this both of them would be visible. c:
If the far ear was in the same position as the close ear, it would look like this. In a 3/4 view of wolves, it's not physically possible to see the inside of the ear because it's pressed back. Angled forward would be a different story. I drew a line over the ears to show that, if the head is not tilted and both ears are in the same position, both of them should be the same height. You did fine on that aspect, I just wanted to point this out to let you know it's anatomically correct.
As for the.. forehead/eye bone, yours was slightly off. I'm referring to the part above the far cheek that's covered by the muzzle. The sort of 'hill'. I'm being confusing, I realize this, bear with me. This line was slightly off, it should be closer to the eye and because of where the wolf's eyebrow would most likely be with his expression, in a neutral position. If his eyebrows are raised, it would be raised up a bit. The bump you see is indeed the 'eyebrows' of wolves, if you consider them to have eyebrows. It's a debatable topic, although many 'toony wolves have eyebrows in order to better convey emotions and expressions.
*Finally stops to breathe*
The cheekbone, the 'hill' underneath the eye, could be portrayed as a bit sharper. It's not wrong if it isn't, once again this is just difference in style. I was trying to show you how it would look if you did it differently, although perhaps the cheekbone on your wolf could be a bit more curved in like in the photo from above.
By the way, I moved the closer eye further towards the far eye. I added a small line connecting the nose to this eye, too. This line, which is parallel with the line connecting the far eye to the nose, is optional to draw, but a good idea to add in order to see where the closer eye should be.
The line by the muzzle could also be drawn more vertically, but once again this is just differences in style and wolf bone/facial structure. In this image the line in the upper lip is more horizontal, here I feel it appears more vertical.
I don't think I talked about the nose. Wolves' noses stick out a bit in the 3/4 view, and they're slightly bigger and boxier. This can be seen here, here, and here.
The last thing I'll mention in this absolutely massive wall of text-sorry for writing so much *3*-is the wolf's shoulder. With the angle you drew in the neck, there should be a shoulder somewhere in there. Wolves don't ever really hold their heads so straight up and erect, they're usually relaxed and have heads fairly low. Exceptions are when they are asserting dominance over other wolves, trying to look bigger, et cetera. You can just google wolf or wolves or whatever to see this.

I hope I helped! c:
