Very nice!
I like the set-up of having an interactive sketchbook! Something I've never seen before. The music was gentle enough to not distract me while looking through this, but it doesn't seem to fit your style just right. But you are very talented! I'm jealous of people who can draw mechanical things so well. Though I'm not a big fan of anime style, they were still pretty nice as well. Continue to draw! I liked this!
