Heat-Lineart

Was first sketching a bit arround, started doing this in school, well, at first it should be a man, but my friend did say like: Is this her back??
I said: This is a man, mdanit!!
He: this cant be a man, look at the curves!
I: Ill show u curves!!

Then i started , making it more feminim.
I think, it turned out pretty well.
If somebody wants to edit it at the pc, just tell meh
