I normally don't like these kind of walls, since they are quite popular amongst newbies that think a 'flat' image with some pencil drawings will make a good wall. It usually doesn't, but yours, yours is definitely different. The whole composition is just brilliant, it really looks like someone has scribbled some stuff first to get the right inspiration and then just drawn that amazing image of Azumanga. The choice of scan is perfect, the scene's perspective makes the whole wall so dynamic and great to look at. Sublime coloring and the well placed pencil just finish the wall completely.
Minor point of critique is the fact that the pencil is a bit too flat, but on the other hand it now blends well with the rest of the scene instead of some weird, hard shadowed pencil floating over the paper.

In conclusion: you just took the full 100% out of this concept and made it a brilliant wall. Deserves to be faved :3
