So recently I’ve been focusing on learning proportions and perspective. I’ve been practicing by using reference, and I found I’ve been relying on silhouettes, negative space, and using plumb lines. the thing is I’m not sure that practicing this way will help me be better able to invent my own poses with proper proportions/perspective. What ways can I practice these skills so that I will not be reliant on copying? How can I use my reference so that I don’t end up mindlessly copying?
