Yay, Loomis! Eyes are a bit high/nose is a bit low for realistic proportions -- probably from the anime influence. Check out this tutorial (helped me anyway), and keep in mind that the distance between eyebrow and (normal) hairline is the same as the distance between eyebrow and bottom of nose. Hope this helps!
