First you need to fix your setup. Your knees are too far back. They should be flush with the front of your arms. This will have your hips a bit lower and the bar over mid foot.
Male, age 39, height 5'5", weight143 pounds.
105 kg (231 pounds) on the bar.
Deadlifting in a pair of lifting shoes (1" heel drop) for the first time. I had been using wrestling shoes (0 heel drop) till now. I felt a bit weird due to the raised heel in the first rep.
I can clearly see some back flexing. I know that I need to gain some more weight, but techniquewise how can I correct this and the other issues, if any?

Thank you Coach Courtland.
I have hurt my back. I don't know if it was from the egregious form in the video presented above or because of the 6 hour drive that followed. Anyway I took a break from squatting and deadlifting today (just did the warm up sets and stopped there). I will come back with a corrected form for further guidance as soon as I deadlift again.
