I don't know how to start the render/color phase. I kinda i have a hard time figuring where i should place the lightining and shadow, idk where to start. I feel that maybe this is a form and structure problem too, because sometimes i struggle to draw things in a way that is coherently with the space and perspective. Any tips on anything are totally welcome | Artwod Feedback
