This is from a game called Monument Valley. Its doesn’t appear to use vanishing points, so it entirely in a flat 2D orthographic view. But I wanted to learn how to draw things from different angles and taking bits of these buildings will be good for that. Maybe. I could try and add my own perspective lines.

I’m not an artist yet, but I got some advice from someone who is. They said that any movement with your hand will improve your drawing.
