>>843102this thread will probably get locked but if this page is any indicator of your current drawing abilities, you lack focus and patience. Drawabox is a great exercise to improve your line quality but you really have to put your mind to it, not just draw a box as fast as you can and move on. Don't skip a warmup, when you learn, don't go to fast and actually try to learn, not just get over with it; change your exercises up to not get bored.
