Howay then icecold, rip me apart:
@85kg, nowt major. Altho doing deads after squats does make it a tad more challenging.
Looks good overall. It's pretty much what has already been said but your hips are too low to the ground and you need to be more explosive as LiE said. Another minor point is you look like your head is a little high so you may want to think about dropping your chin a little to emphasize neutral spine.
For hip/knee position, here is a video of mine and one of my brothers just as discussion points.
You can see that both my brother and I have reasonable form (ignore the knee wobbling, various other reasons for that but as the video is old they are gone now), and the shin is kept much closer to vertical than yours. This will add more tension onto the posterior chain and will affect the loading on the back as you will be closer to horizontal so you obviously don't want to try these changes with heavy weight.
Hope this helps
