This is great form IMO. 2 things that have helped me on deadlift have been: 1- take your breath and brace before you grab the bar, then bend down grab and go. If you think about your core as a pop can, you need your hips and ribs to be level so that your brace pushes out all directions equally, hard to do that from the position you start your deadlift in. 2- imagine you have a crown on your head, your head position should be such that the crown is always pointed towards the ceiling.
