i suppose this doesn't represent only myself; it's pretty ambiguous, but... to me, it means balance, which is something i do a lot of;
balancing concepts like homework, work-work, house-work, art, hobbies... the list goes on. i'm not always very good at it, but things work out in the end, and life moves on regardless of how stressed i am over it.
in some ways, i guess i balance myself physically, as well. most people don't know this, but if you drew a circle around my back, my spine looks like the deviding line in a yin yang (that's right, scoliosis, lololgoodtimes). it's a double curve, and the same angle top and bottom, which means even though i'm twisted, i look straight. (there are puns here which i will not go into.)
the blue in the background... well... that's Zero's colour. a mottled blue-gray. :3
