some might think her white pelt is very plain, but in my eyes i think it makes her stand out. i love her lore and the gas mask concept is very nice dude. i think the brown/green accessories complement each other nicely, and doesnt make anything seem off.
I think her red eyes are very pretty, and i think its special that her eyes are different from her white/green/brown colors.
overall, i see nothing wrong here at all! if you put her in a large group of misc. characters, it would be easy to identify her. the name is PERFECT, has to be one of the most cutest and original names ive ever heard of. (i also love how she's afraid of unfiltered air, that is so adorable haha) but yeah, really awesome character dude! (can i also add i love your art? i love your dA gallery, good stuff)
here's Thrain, by me of course:

alright, i obviously need some ideas on how to make him stand out more, but im looking for simple designs (as if it wasnt simple enough lol but yeah) that won't make him look too over-the-top yknow? some ideas for accessories would be great also.
i'm mainly looking for designs i could put on his legs maybe? his colors were based off of this: https://imgur.com/a/wo3R0
anyhow, i dont really incorporate stories into my characters, but i do think of personalities- Thrain enjoys his solitude very much, unless he is with close friends. he enjoys studying bugs/other creepy crawlies and exploring. he doesn't sugar-coat things much, and usually says things without thinking about it beforehand. but he does has emotions, and he cares about his very few friends a lot. he's just a bit of a mess when it comes to being careful about his tone- it's also something he gets angry at himself for.
