It is highly likely that you were over-harvested with FUE grafts unless you had an unusually high donor density. Ask your doctor what was your donor density  prior to the FUE.  From the pictures, it shows that the FUE was taken outside the permanent zone so many of the grafts may not live your lifetime. Over time, as you continue to bald, the FUE scars in the balding area outside the donor area will start to show and become a problem. The bald area could be the result of shock loss or vascular damage in the donor area from the extensive FUE.  Only time will tell
