If you look at your body in the mirror, you will find many small imprfections. Absolute symmetry from one side to the other is absolutely impossibly in the real world. From your drawings, it looks like a fairly minor imperfection. If you are concerned that the scarring is noticable enough to cause others to take notice, you might want to talk to the doctor about non-surgical things that can help. How to reduce the visiblity of your scars, or exercises that you can do to help fill out your muscles, since they are usually a little more even under the skin and the contour might help fudge the scar lines and make it harder to tell where they fall.
In any case, good luck and glad you managed to get your top surgery done.
