What a pose! A very fun, whimsical look. The legs have a wonderful sense of motion. The right rear could be slimmed down a tad along the upper half. You also could bolster the tail and give it that little shine along the ridge. I think the sharp angles on the face could be brought out even more to give it that Arab look. Similarly, the area around the eye (all those places where the skin is very thin) might be darkened and the nose turned up to further that look. The simplicity of the background is good - not distracting. You might perhaps smooth it out in the distance to create further perspective, though I see you have done something to that effect (thinner lines). The shadow blends in well with the ground, settling into those little dips and curves. All in all, very nicely done!
