Simple Geometry: Taj Mahal

I have been hooked on Geometry Daily lately and it gave me a good idea for a vector sketching project of my own.  It isn't difficult to make a really complex and detailed drawing of a building, but I thought it would be a challenge to make a drawing of a building using only circles, rectangles and triangles.  I also decided to limit myself to four different colors in each illustration.  Expect to see more as the semester carries on!  The first is the Taj Mahal (click on the image for a better view).  What do you think?
