I'm no pro, but I can say what I do and don't like...
I like the solouette of the animal, with the angle of the hill, it's a nice visual. I might've went for a complete siloette of the hill as well, trying to tame the bright sky a little, but that's just me.
The only thing I didn't really like was the subject was fully centered. Personally I like a little variation in this common framing but again, I'm no pro. Just some thoughts!
