As snojones mentioned too much bend in your wrist is potential source of problems.

I've seen many players & students have that much of a bend in their wrist & not have problems, but I think it only works if they have a very loose & relaxed grip otherwise.

Normally I would suggest to angle the neck up a bit (at least on barre chords like you are playing in that image) in order to lessen the angle of your wrist. If what you are doing works, that's fine. But be aware that you might be looking at causing long term problems for yourself.

I cover proper posture in this video.

In this video I discuss the basic mechanics of barre chords. Notice that I have my wrist bent a little bit because I'm holding the neck lower than I usually do in order to make it parallel with the camera frame. But it's still less of an angle than you are using in your image.
