Beautiful, i love her in your style. ♥ The only criticism i have is that this could use more colours for example the northern lights should have pink or green with a yellow tint. (in real life they're never that one coloured) and perhaps also adding some backlight to froslass, she looks like she doesn't belong there since all the light should be coming from behind her.
nevertheless, beautiful. also i love the way the "brushwork" is always so visible in your art. ♥
