Have you taught yourself? If so, good job, you look pretty good technically.
One point I picked up on is that your hips are incredibly low in your starting position. In some of the snatches they look lower than your actual knees which is a pretty weak starting position to be in. Because of this it also appears that your shoulders are behind the bar right from the start of the movement which means the bar is having to move out around your knees and then back in again during the first pull. Now it doesn't seem to be affecting you massively at the moment, but I expect this is because you are able to control the weights, whereas when you're snatching 1.5x BW it won't be as easy.
It's an easy problem to address. 1) Keep your hips up higher 2) get you shoulders over the bar a bit more (this will probably happen naturally from raising your hips)
Once again though GOOD job. Once you've increased your leg strength a bit I reckon you'll be able to shift some decent weights
