This is the character design for the one of the lead characters in my radio play, "Unexpected Angel Force: SERAPHIM" currently in production. It is a "dramedy" giving homage to and poking fun at magical girl anime.
The "floating head" is Haelie, who becomes Mikomi when she transforms. The head is there to show what the real girl looks like.
Mikomi is supposed to be a nod to magical girls like Sailormoon and Luchia from Mermaid Melody Pichi Pichi Pitch, thus the general formation of the bangs and the pigtails, as well as the use of the color pink, which is a common magical girl or shoujo character color.
