This picture is AWESOME. You have absolutely amazing lines, even greater coloring skills, and the perspective is amazing. What kind of training do you have as an artist? You seem like you've had to have taken a few classes. If you're completely self taught I'm gonna wanna die of envy. Did you have any kind of reference for this? I mean, with or without, you've got a really great perspective here. The only thing that looks off would be her right breast--it looks a little squished, but I think that might be because of the positioning of the buckle. And even as an excercise, this image doesn't loose any originality or spice. Her expression is really sweet, and her pose is showy without being overstated.
What medium did you use for the colors? It looks like watercolors or CG. I really like the shading, it's soft but doesn't loose the anime style. I'm most amazed by your lines, though--I strive to do lines like that (and fail miserably, for the most part.) What type of pens do you use--or do you use the computer for this?
I hope to see more of your uploads in the future. I can definetly learn a lot from studying an artist like you!
ye accomplished the perspective really good
