So she's like her namesake and everything she touches turns into gold or she has a similar but different kind of power and everything she touches turns into a weapon? That might be a bit inconvenient as far as eating and drinking is concerned XD Great pic, love that flowing hair :D I reckon you could have totally made daytime work but think the decision to make it night instead was a good one so now you got the nice contrasting colours :)
Everything she touches turns into gold (not very original...) which then she uses as weapons! I made her wear special gloves made out of chain mail so she won't accidentally turn everything into gold >u< I think dark shade suited her the best too!
LoL special gloves so she can eat and stuff is not a bad idea XD
