Thats not bad, it just needs a couple of adjustments, especially on one side where its more forward than the other side.
I've marked those areas.
The flaps will help blend the hair into your own natural hair at the hairline and prevent you having a wide looking forehead.
You attach them in the same way as the hairline.
I would have thought a 65% density was good for you, but you need to check this with John.
You also want a 'graduated density hairline' where the density is lowered at the hairline by at least 5%.
Again John will be able to advise you on that.
