Deadlift

I've been fiddling with my teqnique for a while now and this is from my latest session

I've been having trouble with rounded lower back but this looks ok doesn't it?
I try to focus on leaning back with weight on heels. The downside with this technique is that I have to lower the weight quite a bit (as you can see in the clip, 120kg is slow. Usually my work sets are around 130-140.

What do you think? Am I onto something with this technique? Any comments appreciated

It seems you are being pulled forwards too much. Do you feel this? I would try lowering the hips slightly and getting the legs involved more.
