Wow, these are really great!
My tip would be to remember that hair sticks up off the head... in a lot of these it looks plastered flat XD

Keep on practicing, and you must show us more of these when you do~
My fault, I messed up when pasting the link across, and the direct link doesn't wanna display for some reason anyway XD This one should work now, the hair tutorial's about half way down, but there's some other tutorials on there that you might find interesting too XD http://www.howtodrawmanga.com/howtodraw/tutorials_all.html
Sorry that took so long... and the hair isn't "stupid" though, just not as good as you could make it look XD
And meh, it depends what style you're going for... I've seen people use absolutely huge ears and make it work perfectly. You do have to find a balance with the other elements of the face though (something I never can XD). But you're not an idiot because of it, that's just how you draw :3
