Something fun for everybody to try. I actually learned about one point perspective very very early in my life when I watched a Reading Rainbow episode about Trompe-l'œil [link] painting. I've been fascinated by the making of large and realistic paintings that fool the eye, making a flat surface look like it can go on forever.
I had fun drawing city streets and designing buildings. I would draw store fronts and put objects in the window... pet store, fashion store, whatever. I love looking at architecture drawings and other design related art. Everything you are learning has its application in the real world.
