and btw... if you decide to edit the tat pics, do it the propper way. The way you're doing it, I saw tats on people with unnaturally "green" or "red" skin.
About photoshop: Sorry there are people who can tell if pics have been edited.
About the tat: If it's not on an albino, then it must be done on a pig with a blonde wig.
About winning contests: Wanna hear some stories about judges and/or suppliers?
it's sad that some people have to tweak photos to make them look better.
Making colours stand out like this wouldn't have anything to do with technique... it'd be about the ink, and it's just not out there.. otherwise every decent artist would use them
