These headshots are really fantastic! These boys are all completely different and unique! I have never seen anybody who looks even close to the designs of any of these young men. I especially love the use of color! The gradient effect you created makes these headshots stand out even more. It is even more fantastic that you used pencils!!
There is only one small thing I think is a little odd: The young man on the bottom left, where are his horns coming from? I cannot really tell. However, it may just be a weird quirk of mine. Keep up the great work!! ^W^
