Tough to really tell a whole lot from just one picture. Several angles, especially from directly above you looking down can give a better idea of what things look like. One picture can be deceiving.
But saying that, it looks like you anchor with your hand vertically flat against the rear portion of your face. With your head pointed toward the target (depending on your bone structure) it can be tough to find a SOLID anchor point back there. Lots of muscles in the lower/rear jaw in that area along with muscles and tendons coming up from your neck.
Look at D.Cousin's pic in the second post. See how his hand is more horizontal? He's picking up the bottom side of the jawbone more towards the front of his face. That gives a much more solid and repeatable anchor.
But archery is all about doing things in a repeatable fashion. Some people have horrible form and/or a drawlength that is way off from what is considered "good", yet can shoot lights out.Fairly rare, but possible. Releases all have different lengths from grip-to-hook, so going from one release to another may alter where your hand is on your anchor quite a bit. You need to find the best anchor FOR YOU, and then adjust the d-loop and bow drawlength to fit that anchor. Doing it the other way by adjusting
your anchor to wherever the d-loop and bow drawlength may be isn't always the best idea. As I think you're finding out....
Don't know what release you were using before, but to get your knuckles to the underside of yourjaw, you'd have to shorten the draw quite a bit.
