Coyote Sunset

Quick painting in ArtRage. I've had an image like this in my mind for a while, especially wanted to try the colourscheme. The coyotes were a last-minute addition, but I like the look of them. Originally I had some tufts of grass here and then, but felt it became too cluttered -- any comments are much appreciated! I have a picturebook project in mind for which I'm gonna need to do a lot of quick landscapes and background, so I'm trying to train my hand and eye a bit concerning that, so feedback is great!
