The overall feeling of the heads is good. What's lacking is an understanding of the construction of the head. Even if you want to do more of a cartoony, anime style, you have to learn construction in order to know where to place your lines. If you are open to advice, I'd just focus on learning each of the following, just commit to watching one Proko video a day and then doing one drawing from life or a photo, trying to apply what you've learned. -the loomis head -learning how the jaw and the ear meet up -learning how the neck connects to the head (a cylinder on a ball) -learning the structure of the eye -learning the structure of the nose -learning the structure of the mouth.

Hey aaron, I don't know if you are going for a real or anime face, but they all have things in common. I did a quick sketch to show you how to find the proper proportions to the face, I hope it helps :)
