Apparently this is a PSO character (though likely from the 2016 MMO or whatever, her name's apparently Quna). Just about the only good render I could find that was PSO-related. I feel like I could have done much better with her (and it ended up a bit weird), but I'm not used to starting off with such a bright and saturated drawing. Might revisit it later if I have a brainwave on how to make it better, but I probably won't. Now I have a signature that fits the forum. =P
If someone wants the original drawing I found, PM me. It's absolutely massive (2500x3500, 5.2MB) so I can't upload it here. Or google for it, shouldn't be that hard.
