What's your question?
Hi,
I know this will offend your artistic sensibilities. I know where you like the bar on the back. But I have some pretty bad shoulders. So I hope you can suspend your judgement and have a look at this:

I'm a bit concerned about my lordosis. I might be in too lumbar extension. I think this is why there's that hip movement. I'm trying really, really, really hard to keep my abs tight throughout.
Thanks.
What's your question?
It could be. You'd certainly be better off limiting the movement of your low back, but you already know that. What's wrong with your shoulders that prevents you from putting the bar lower?
Tell me about your sickness.
Wear a belt & get your shoulder fixed asap.
