Purple

Hello! It's my first critique and my English is not very good, but I will try!

Let's start with the background. The combination of cold colors let the atmosphere seem very tranquil. But because of the salt technique there is some movement in the background. I think about the sky when I'm looking at the BG. It seems as if the wolf would fly.
I can't see any mistake in the anatomy of the wolf. The fur is well drawn and not too detailed, but not too less. The color for shading you used fits perfect with the background. The eyes of the wolf look in the distance and underline the feeling of levitation. The only thing that bothers me is the head. It looks a little bit edgy and not so smooth like a wolfs' head should be. I don't know how I could describe better. I hope you understand.

All in all it's a great piece of work!
