Building drawing with pencil and watercolor

Hello fellow steemians,

Here is one of my drawings which I drew as part of a university course back in 2007.

Unfortunately, I don't have the process photos of this drawing. The idea of the course project was to start from basic 3D shapes, organize them into a complex shape, and then come up with a buiding from that model. I modeled the basic shapes using blocks similiar to lego blocks, then used pencil and watercolor to imagine the model as a building and draw it. Hope you like it.
