Flame wolf

The leg that's sticking out's elbow is a little too low. If you look at a wolf or a dog, the elbow starts at the stomach and so the bottom part of the leg should be much longer than the top part. I do really like the colors on them, they're very nice. For the shading, I would maybe blend it a little bit. The background is also very nice. You're really great at picking colors!
Also, what did you use to make this?
