Anthro Challenge: Time's A-Ticking

Those last moments of school when you're just waiting for it to end, but the seconds pass by so slowly....

Still working on perspective and poses; tried to make it look like Matsuri was leaning back but then just ended up making her proportions look skewed. |D
I actually don't like this one very much, but I learned some about shading. I also learned that I don't like drawing indoor backgrounds; I'm probably going to stick to more natural ones from now on.
