Here's a new sig I made for Mira Selendis (The chimera project's main character), using the Order Light Carrier designed by Jinx.
I may need to remove the pink/purple strip in the middle. The background behind it is two different space backgrounds - one green and one blue - merged together, meant to mirror the colors of yuna's eyes in the picture (one green eye, one blue eye - the backgrounds if 'flipped' opposite of hers).
edit-
I've also got this one, which removes the background and uses transparency for it. Not sure I like it better though...
