Really great design and rendering. I'd 1/2 agree with whoever it was above that mentioned the context. It's obviously an urban building but it's shown by itself which seems a bit disjointed. However I'm not sure I personally mind that all that much - a bit of artistic license. I think the important thing is that you get a good idea of what the building will really look like. Appropriate context would be great but sometimes in a time crunch you have to prioritize. Hopefully your school critics will understand that.
I really love your sky! Any hints as to where you got those? Or did you make them? I love the subtlety of them. Gives me something to strive towards. Still looks realistic but doesn't detract from the building.
Is that a garage on the bottom left? It looks like you can see through it, yes?
