Drawing Heads with the Loomis Method

I've been practicing drawing heads lately using the Loomis method. I think I've got the basic proportions down, but now I need to work on drawing features like the eyes, the nose, the ears, etc. The eyes and eyebrows are hardest for me; if they look wrong, it all looks kinda wonky.

I'm nowhere near where I want to be yet, but I'm not unhappy with my progress either. Pretty soon I may have something I'll feel comfortable sharing, at least once I figure out how to take decent pictures of my drawings with my phone (I don't have a scanner or even the space for one).

My favorite video tutorials about the Loomis method so far:
