My fursona has a celtic band style arm tattoo(and may consider one in real if I ever get one myself), though I dunno if that counts as 'tribal' ^^' At the very least I have ancestry from that region and would try researching specific designs/meanings in case I do so...
Also, I'm kind of jaded by some modern art stuff. I respect time, effort, and ideas but sometimes things get really pretentious. I rarely have a profound meaning behind things, I just make stuff because I like to. Also, the prices on some pieces... Pollock, I'm looking at you.
