Great work! It's really awesome to see someone fight through metal obstacles and achieve something they thought was out of their reach.
On top of what Greg already provided, I humbly think that you could improve your rack position. It seems like your bar is resting on the clavicles and palms rather than across the shelf you should be making with your shoulders. This is probably leading to some bruising and pain in the wrists. You could correct it by flexing your lats, which should help you raise your shoulders and create that nice rack position. Think about doing an old-school lat spread pose that a bodybuilder would do.
Other than that, nice job! Keep it up. I hope what I provided helps you.
