Assignment: Arms Up! - Hatsune Miku sketch

The sketch of my entry, I'm planning to ink and color it, still having 3 days until countdown, so I'll be able to make it very good... hopefully.

I'm getting a little addicted to high detailed drawings, so I'll ink it with a lot more details in the hair, eyes and clothes, if all go right I'll have time to do a good coloring too

I've just made a simple shading, the parts shaded will go black when finished, the others are gray, yellow, blue, green and red, as expected from her.

This is also my first vocaloid drawing ever, turned very well I think, I had some trouble doing the shirt and making the hair flow naturally...

Hope you liked it, thanks.

PS: The name of the assign is "Raise your Arms!" not "Arms up!"
