Thanks for the critique, I'll try to work on my color skills during my next project!

Prepare for critique! I think the sky is a bit too light; the white parts of her body are hard to see. I think a highlight for the grey parts of her fur would be good, too, because she might fit better with the rest of the piece. Everything else has at least 3 shades, while she only has 2. I also think the ground is a little distracting and busy with the way it's shaded. Perhaps simplifying the shading there would be good. Try taking away some of the darker shades in parts of the soil and use it more sparingly. ^^
