pointer: OHPs are intense as fkkk, you don't want your mate to be saying "do you want a picture or video" midrep
LoL.
In all srsness, I have always felt it to be a really technical lift because it stresses my fragile wrists

I think I just about got the hang of it. If you're able to hold a bar for front squats with a grip (not with your hands crossed), you should be able to attain a neutral position for OHP when you unrack or inbetween reps.
hmm, I have my wrists just outside my shoulders just because if they're within my shoulder width, my thumbs would get pinched in between the bar and shoulder. I rotate my elbows all the way forward so they are pointing in front of me, essentially resting the weight on my anterior delts.
The descend is an important part of the lift because so many things can go wrong. Your downward motion if you watch the video, was the same problem I was having. Your elbows flare outwards first, then you change your mind midway and decide to descend with elbows forward. It's too complicated. It took me ages to fix that, and I don't think I have it fixed yet. Not entirely a problem, but when weights get heavier, they are just too much to think about.
That's all I have to say. All the best with your lift.
