How the FUCK do I learn to draw heads? I'm sure it's all my fault and I'm doing something wrong, but I just can't get anything right... I do construction according to the loomis method but all the heads I make look lopsided, weird... it's getting so frustrating I wanna smash everything.

I have no trouble with anatomy (I mean that I still have a long way to improve but I "get" it and I can make things that don't inexplicably turn out wrong no matter what), but heads are so fucking difficult for me. Are there methods other than Loomis that can help a retard like me with them? I see people effortlessly draw nice, well proportioned heads while I have to make countless measurements and attempts to get something that looks vaguely human.
