Cool modeling girl 🙂
I wouldn’t worry to much about good looking topology for the moment. You will automatically get better at it the more you do it. The most imported for now is that you manage to make the shape as the reference. You can use the smooth tool in the specials menu if you do not select the outside vertices and make those looking good manually.
You are right, that vertical line is not a bent, now I see the other side too. These are the marks of the ‘V’ press the object was bent into. I found an image on the net for your information how stuff works.
