I really like the way your draw paws and ears and the pose is really interesting. The anatomy overall looks pretty good, the front paw (lifted up) looks just a tiny bit wonky to me. The other front paw looks bent a little too far forward after the bending point in the leg.
The paint splatter background looks pretty cool, it doesn't overpower the dog (Wolf? I can never tell, but that's just me) but instead adds to it. It's cool how you shaded with blue.
The lineart is somewhat rough, but it doesn't subtract much from the overall drawing.

Pretty! Good job on this drawing, it's well executed.
