Mercado Canted Shot and Macro Shot

Canted shots have always been interesting to me, I always understood it to be the diagonal lines catching the eye, and the instability of the image catching the feel of the shot, but for some reason I have so much trouble handling them. I know that if I were handed a camera, I'd be able to shoot the scene just fine, you know ~just tilt the camera~, but as an animator, drawing the scene becomes very difficult for me. I end up losing track of the perspective, and my diagonal lines start migrating back to horizontal/vertical lines as if they have a mind of there own, despite all my best efforts to train myself to draw more dynamically. Maybe its because backgrounds aren't my forte, I should work on those.
I've always thought of Macro shots as just being Extreme Closeups because I thought they functioned the same way, but I think it's interesting how Mercado differentiates them by the closeup's function to the big picture, and the macro's function to the narrative.
