See, I didn't know that (About the Arabian wolf.) but if I had, the score might have improved. One should always site references if they used the reference in the drawing. However, here is another tip.
Your wolf is pacing. Both legs on the right are forward, both on the left back. This is not a natural gait for a wolf, and I've never seen a photo with one pacing. Their legs will always move in opposite pairs. Look at your reference.
That's what happens when someone keeps looking at an individual artwork, they find something different each time they view it, it's human nature.
Anyhow, good luck next time. I can see you are a good artist, and there are some much better competitions out there that you could get some nice prizes in.
