Weasel - HSR art style study

I've been really into Honkai Star Rail recently, so I wanted to try to draw one of my OCs in its artstyle. I tried to add as many details to this design as possible, but I fear it was still not enough.... Maybe I'll attempt to draw a background at some point so that it becomes a proper splash art? who knows

Her name in HSR would probably be her title, "Weasel". She would probably be ice/destruction?
