Knight's sketchbook

[JosephCow]

Before burying this post in pics I'd like to ask you guys for exercises suggestions to increase spatial awareness and line accuracy. I'd love to hear not exactly what is done in schools but what you like to do, the weirder the better.

Judging distances, angles in 3D shapes and curvatures are hands down my weakest points. They don't come naturally and so far I have not much success in cultivating muscle memory for these."

Do you mean in terms of drawing things at different angles like rotating them, or drawing what you see from ref? I feel like it's two separate goals because if you are trying to get the accuracy drawing from ref or life, there are techniques and stuff to 'flatten' the image so you can look at angles and shapes objectively. But then if you mean instances of trying to figure out how a curved form would look at a certain angle, or in space I would do different stuff, but that's probably my biggest weakness as well.
