This is a pretty good start for a character design. I like the style and the overall shape of her silhouette and your base colors are at a good starting point I think. That being said there isn't enough variation in the values of the colors and this leads to her kind of blending into herself. Her cape should be darker than the front part of the coyote's head and there could be some highlights to bring out the shape of the muzzle some more. Also try darkening the entire coyote in general to further separate it from her skin tone.
At the moment the huge braid in the back along with the front part of her hair and the cowboy hat all create a sort of blur of dark grey. Try making the hat the same color as either the tan of her shirt/boots or match the coyote and put a black band on it as oppose to what it currently is.
Also to add a greater sense of unity in the color you could add some tattoos or war paint the same blue as the coyote's eyes.
I get that this is just a character concept render type drawing, but a better background would definitely help, nothing complex just something with a little more personality than grey. Look up pictures of the desert to get an idea of the colors she'd be around mostly.
Hope that helped in some way, keep it up, man.
thanks a lot! those are all good points :) if you don't mind me asking, what experience do you have?
