Lol the old one is from like a year and a half ago, idk...its really old though. Umm....the coloring was REALLY crappy, absolutely noo detail in it at all. I really like the pose and the anatomy is, meh, ok, but the coloring absolutely STUNK! I know how to color wayy better now, so the one on the right(unless you are blind) is obviously my new(and GREATLY improved) version.
Remember that your only competition in the world of art is yourself. You only have to be better than you were a long time ago...and it looks like you're kicking your own ass and taking its name while you're at it!
I agree. The coloring on the new one is an improvement, but the legs are a little awkward. The left hind leg is oddly shaped in my opinion, and the paws are more demonic or stylized or something. In the original, you seemed to have more of an understanding of the direction of the chest. Other than that, both are still outstanding works.
