With those hairs and a normal skin, she could be a cute mutant of some kind.
With a a skin such as this one my first thought was : Lovecraftian’s Deep Ones’ Half breed (although her eyes are a tad too human to fit the bill, granted).
Other option would be to go sci-fi all the way but then her clothes don’t fit the bill and we’re in the wrong pack.
What was your idea ? “my high-school pal from Mars” ? or something like that ?
