Mm, nice!
The back ground is really busy, takes away from the drawing. But I really like this piece. The steam-punk meets elegant quick sketch-up feel is great. I like your work. Looking through your album I see you have a bit of trouble with hands but, I'm sure you're aware of that. And don't worry, they're the hardest thing for pretty much Everyone to draw. :) Keep up the work. I'm diggin' it.
Also,I really love the clouds of music or whatever that is supposed to be. Great style and smart idea. :)
