Not great at technique critique but let me give this a shot:
First thing I noticed is you jump forward to get under the bar. From looking at your video, you don't stay over the bar long enough. Your first pull starts pretty far back--your shoulders look behind the bar from that angle, even--and you aren't patient with the second pull. When you hit the knees, before immediately leaning back and shrugging up think about straightening your knees out (pushing them back) while keeping your chest over the bar, and keeping your back tight so you pull the bar close along and up your thighs. It's like the starting movement of an RDL up to about mid-thigh, at which point the double-knee bend and hip scoop and everything kick in.
Not staying over the bar is probably why you're kicking it forward during the second pull.
Clean looks very nice, the video has cut off the beginning of the first pull though. You're definitely staying over the bar more. I would keep your back tighter--if you slow down you can see your shoulders rounding forward as you pick the bar up off the floor. Pull them back and down, really think about tightening your lats and pulling your shoulders together. For me, keeping a nice tight back is the difference between a lift feeling heavy as sin and light as a feather. There might be a bit of arm pull during the second pull, but I may also just be seeing things.
You can see the effect of the loose back as you catch the clean. Even though the weight is clearly light for you--you're catching it above parallel and riding it down--you round forward during the catch while squatting it up out of the bottom because you simply didn't catch it with a nice tight back to support the bar.
Jerk drive is good and powerful. Again, gotta keep that back tight during the drive though--you tip forward slightly at the bottom while driving up.
Your footwork could use some improvement. Your back foot splays way back and sideways. If you draw a line across the starting position of your feet, I think the distance from your front toe to the line and your back toe to the line should be the same. However, I've had a number of coaches tell me if you've got the drive to get the jerk up there and lock out hard, you can make up for crazy footwork.
If any real coaches (Greg?) want to chime in and correct me that would be awesome.
