My feedback is as follows:
- Your first pull looks good.
- It looks to me that the bar's bouncing off your hips. You don't want your hip drive to overwhelm the leg drive through the ground.
- Following from the last point, the bar just zooms out in front of you. This is why you feel slow getting under the bar. If the bar's way in front, it'll take you longer to get under it

Not to mention having to chase after it.
- OHS looks good to me.
