Sketchup WIP:Elementary School

Ok, anybody remember I'm an architecture student?

Yeah, I'm in a middle of the second project that I have to design an elementary school with 12 class and many more other rooms for many use.

This is what I came up with Sketchup 6. And I'm posting this to get some of you guys' suggestions about it.

This is just a WIP that I need many more inputs. So, I want to know how the schools in your place were built. Like what kind of room they have, where they place those, and it'll be great if you guys can give me some photos of your schools.

Again, I REALLY REALLY REALLY NEED YOUR SUGGESTION about this, tell me what more I should give it.

Thank you so much
