I like what you did, but I think it would blend better if her hair was black... Plus she looks a bit LQ imo.
Was going to say also vector her or de noise her to give her more quality other than that looks sick.
yea i agree with everyone above, something needs to be done with the render to have her blend a littler better. i love the idea, its very unique, and it would make an awesome abstract sig. try fooling with the render to get a better blend, agreen with the vector idea.
