Hi Kyra,
Nice start with your animation. Over all it feels a little soft. I think the front of the body can come down a bit, the chest looks like it is moving up down too much, in this case it looks like it travels up and down more than the hips. Really pay attention to the shapes a wolf makes when rolling off its front paws and the relationship between the shoulders and the front legs.
If you provide a loop in profile, I can do a little draw over in syncsketch.
