First, you need to decide what you want to draw, and give us as more information about your problem as possible. Dog or Hyena or Ghoul.
Second, this is harsh to say, so a lot of people don't want to answer to this kind of posts, but you need to learn to draw. Nobody idea can't help you with that, cause I'm sure that you have very clear idea but you can't put it to work.
At the end, here is my quick edit (if you can call it that) with only few colors at the same resolution as yours, and I hope that it will help you, at least to decide which way you should go with your efforts. Good luck.
