The looks/elements from Mahoro and Haruhi?

As far as I can see, she only bears the elements like the eyes and the hair that sticks out (although you should be able to clearly see both sides, although this image, or perhaps the author forgot to put of the left side) from Mahoro and bears no resembles from Haruhi.

forgot to put out/draw*

"wished some kind of edit mode existed"...
