Quite a good artwork, with little to complain about. The colours are all nice, and the proportions are good, especially on the back legs. I'm not totally convinced about the front legs for some reason, and I'm sorry that I can't give a more detailed reason as to why they look strange to me. Maybe the 'wrist' seems too high up, but I really don't know. You seem to have a fair idea of what you are doing, which is a good sight.
