I wish that I could sign up for this, but I do not possess the necessary photo skills.
KryOnicle, that is just excellent!
Edit: I just wanted to add compliments for killstarz and hkado as well. killstarz, that is really well done. I especially like the added background and what appear to be texture changes to the hoody. I also like the color effects in the iris.
Hkado, your work is so dark, scary, and so wonderfully red. That is a fantastic image, and I personally think that it would make a fine avatar.
If you want it let me know add I can add text to it if you would like.
