One thing I'd like to point out is you have very dark hair and what looks to be lighter skin. Your hair shaft diameter looks to be pretty large as well. Those two things could lead to some pretty noticeable scarring were you to go FUE. Even with a small procedure of 1500. Whichever route you go, you may have to keep your hair longer regardless.
As a side note, I know you are 35 which is a relatively later age to be getting a transplant. However, you have a high likelihood of losing more hair in the future. You won't be happy with an aggressive hairline and balding behind it at 55 or maybe even 65. If you put any hair at all in that front bit, that is a very aggressive NW0. Be prepared to need a lot of grafts to maintain that hairline for the rest of your life. It never goes away. If your plan is to shave it later in life, don't bank on dodging scarring by getting FUE either, as you will likely need larger punches to accommodate your thicker hair. Going gray will help but won't completely eliminate the problem.
Getting a hair transplant sucks. It is a last resort and creates a host of problems. You should only get one if you are willing to trade your current problems with all the problems that come along with a hair transplant. You might even get hosed and get the worst of both worlds, due to low graft survivability, permanent shockloss, or keloid scarring. Very, very rarely will you not notice a difference in transplanted hairs vs. native hairs when you look in the mirror every morning. It's not a perfect solution.
That being said, the two cases that @ADuckwithNoHair mentioned earlier were both FUT. I am a firm believer that FUT gives you the best chance at graft survivability, which is important if you want a one and done procedure. It's also much easier to fix a bad FUT donor area as opposed to a bad FUE donor area. Diffuse thinning in that region is a bitch.
