Thanks for the input, but I designed the classrooms the way I did for a few reasons: first, the building is structured in such a way that the sides of each room are against each other, making windows only possible on the ends. Second, classrooms - at least the ones I grew up with - aren't always symmetrical. Actually, if I designed every classroom to be super symmetrical, there wouldn't be any diversity in them and it'd just look boring. If anything, they resemble more how my own former high school (a small, private school, much like St. Giles) used to look.
Also, that area's not just a reading area - it's got a computer for students to work and print on too, though it's obscured in this shot. This is the English classroom, and it's not that dissimilar from how my American Lit classroom was structured. So maybe we can chalk that up to different school experiences? idk ¯\_(ツ)_/¯
(Oh, it'll probably also look better once I program more NPCs in it. That could be it too.)
