I've been making these pics since the first year we could and there has ALWAYS been a shortage of X and Zero pics.
seriously google that s*** up. It's so hard to find good X pics that are good quality. Zero too. So matching them is a double asspain. I know a lot of people hate rendering Zero's sword because it's a light blue/white, too, so he may be causing the problem in general as nobody but me seems to have the patience to hand render things
