I've recently been practicing changing viewpoints and perspectives in my drawings to enhance creativity. I feel like if I have one piece of good advice for new illustrators, it's to think about different ways to represent the same scene. Imagine that you're a cameraman and you want a different angle on the scene.
I really love seeing the creativity of artists who think of unconventional viewpoints! In the sketch below: I tried drawing a bicycle from directly below and from directly above; I also threw in a sketch of Totoro and the catbus in the rain for fun.
