R.I.K.A Seravee Type Avalanche

This is just another undecided concept of a character of mine for my manga that i have been working on, and well more or less is for her version 2 tranformation ice type model.

Though i did took some idea from "Black Rock shooter" 4 a buster gun that Rock uses but Cyber it up abit, maybe some of the "Seravee Gundam" from 00 4 the back wing piece as u can c on her back, and well Rika looks ok so far but im just not sure on the concept of her so i need more opinion first so tell me what u think?

Oh and i kinda 4 got 2 mention that i also got some help on designing her knee cap from my friend here ~4164120003 and his concept [link] back then so credit also goes to him with the idea.
