well, ur a NW5 on ur way to a NW6 so 2700 grafts aint not gonna cut it. u need at least 5000 grafts and probably closer to 6000 and maybe even 7000 grafts depending on ur head size if ur wanting density.
ur not gonna have density with 2700 grafts. in fact, ur still gonna look pretty bald with only 2700 grafts. you asked an honest question so I'm given u an honest answer. most of hair in the middle has miniaturized and will surely lose the battle in a few years.
and as far as the hairline I'm not sure wat ur doctor was thinking. I think he was trying to achieve an irregular design to appear more natural. I think he missed that boat by like a mile. I checked his website and can see that he used that same approach on this guy Growhair-Before and after photo's FUE follicular unit extraction | GrowHair.eu
it can look natural on some people but those irregularities are usually up front in the hair line. not on the side in such a drastic manner. but watever once it grows out it will look better I'm sure. thats pretty easily fixable imo.
seems like u have quite a bit of donor hair so id say u cud extract another 2500-3000 grafts. ur probably gonna have some shock loss since many of those hairs are weak so ur definitely needing a lot more grafts it ur lookn to make any drastic changes to ur appearance.
ur doctors FUE work on his website doesn't appear to have very good yield on some of his patients. I think his skills are not worth going back to for further work. there are far better choices out there but ur guy is cheap. looks about $2 a graft.
