Hey! It's been a while since I checked your work out. Angel Academy, is it? Congrats! That's an amazing school, I'm looking forward to see your work from it
Your colouring has level upped many times since I peeked in last! Wow, your skin colours especially, they've gotten so natural. However, it's mainly the basic anatomy that's still throwing you off ocassionally. But I think you know that yourself and it seems like you're tackling the issue, so all the best of luck to you
Very nice sketchbook here. Good studies. You seem to have some problems with drawing heads/faces. Often on your portraits eyes are placed strangely which gives the face an unnatural look. It's not always evident then you draw/paint a face in front view. But then you paint turned heads it becomes much more evident. I suggest you spent some time studying head/face proportions, check out Ron Lemen's head tutorial here on CA http://www.conceptart.org/forums/showthread.php?t=84105 to get started.
I'm sure it will help. Keep up the good work.
