Looks pretty good. Your legs might be slightly too bent (unsure whether that would disqualify mastery though), but I would say you are reaching the minimum required height in your arch ups and keep a solid tempo. IM looks ok to me too.

I would wait for a more official opinion before moving on though.

There's something funny with the legs, they should be straight for sure, it looks like one is and the other isn't. It's hard to say with the camera placement though.

On the iM, looks good, I think you could add more weight.
