The muzzle should be long and pointed like a coyote, the only difference is that instead of a coyote nose, there are two slit-like nostrils.
Also, the sensors are missing from your entry. Check the references for where they should be(they are the round nodules just in front of the eyes on the face in all references)

Muzzle a little more pointed and the bottom sensor should be further forward

That's better on the muzzle, i still think the sensor should be up more, closer to the center of the eye rather than so low

Much better
