Isometric Bell tower

Isometric Bell tower - student project

I tried making the bell tower next to my house, as I've seen it lots of times. Here's a pic of the original. Located in Gracia, Barcelona, Spain.

I couldn't recreate the parts that are hidden, like doors or windows at the top, as it is difficult to draw partially hidden objects. Nor the bell at the top as it is not a trivial shape.Isometric Bell tower - image 1 - student project
