First of all, good going on posting a video! Too many people don't and end up using bad form over long periods of time.
Are you going for a romanian deadlift or conventional deadlift? It looks more like a romanian (you are really doing a romanian deadlift) It looks like the back is a bit flexed when you lift it off the floor and when you put it down.
On to the lift:
It doesn't look too bad, though I would focus on getting more of an arch in my lower back. If you look at the lower part of your back you can see a little bump, that's what worries me.
As you start moving your hips back, just focus on arching the lower back. You may need to do a bit less ROM in order to do this
Also, lose the shoes, just do the DLs barefeet. The shoes look like regular running shoes or something. I bet the sole is really soft, which is great for absorbing impact from running, but not so great for stability when you are lifting heavy things.
Also, keep your shoulder blades back and your chest out.
Keep up the good work! And it's nice seing someone actually doing deadlifts for a change
