well besides the fact that it's well done, there's alot of potential in your art, and I've always been interested in seeing a person reach high levels and realize there potential. Quite fascinating to see it grow. Alot of people on my list are budding artists, I've seen many of them improve over the years. I guess I'm weird in that way, i like to see progress more then perfected skill lol. Though that's not to say its not interesting to see that too.
Also, as a sidenote, i don't mean to belittle your work by any means, i see you gained great skill in your art works, far better then me anyways, especially in your tone and coloring.
