Practicing perspective (last year)

Here is a drawing I done last year, in 3ºA ESO, in the class of arts and crafts. We had to draw something related to perspective, and I thought a village would be interesting. Nobody told it was easy, and wasn't so. However, I enjoyed drawing it but it took many time. Although I really like the final result, I prefer not to do this kind of drawings, as they are very technique and sometimes difficult.
