A long, long time ago, in a school no so far away… I learned about perspective. I used to make pretty complex drawings with it on paper, but as a starter for getting back into it (and doing it digitally) i went for something relatively simple. 2 houses and a doghouse. I’ve left the “help lines” visible for an extra effect, and added some cheap shading to make it more visually attractive. It’s a two point perspective, with one of the two being offscreen.
