I want some sort of reboot, but I don't know where to start learning, going to the art university here is not an option, it's not helpful at all for illustration, they just do painting (their study plan is from motherfucking 1940!!!)
haha yeah I know the classy schools. I'm afraid you have to start with the basics. Do still-life with pencil, draw objects and use light. try to draw it as realistic as you can. Do it often, use different objects with different materials etc.
