Heres a few ideas that can help:
-Have your initials/logo/name stamped on your head or body

-Suggest at the improvement section of the classic part of the forums any suggestions you think is helpful for the whole upload system

-Send an email to [email protected] having your head/body proofed of original copyright. This makes sure that they know your the original creator of the Head/Body (They know which are edits/recolors and which heads actually aren't theirs). Helps in many ways (What Higbey did)

-If you feel like you're afraid of having your graphics stolen, don't upload it

The head looks awesome x3
I don't know how you edited it that quickly but it sure looks sort of a change
(Where the heck have you been? I haven't seen you on these forums for long! D: Lol)
