Architectural drawing

I finally came around to creating a project for this class. I'm taking a drawing/painting class in school and for my perspective assignment, I came back here and rewatched the videos (still as awesome as when they came out). So here is now my project I did for my school class and it should be my project for this class as well.
It's a traditional art class, of which I only know how to do graphite, so the teacher pushed me to do a mixed media piece with graphite, ink and watercolors.
I started to pencil in the perspective and main shapes in.
Next up, ink:
