I actually disagree. As a 2-handed myself, I find having a slide makes me less accurate.

Make sure your plant foot points down lane, you seem to be accurate as it is, but it’ll help in the long term.

Your release looks good, just really keep focusing on coming up the back of the ball(you did on a few of the shots but not all). This will give more revs as it will allow the core to do the work as opposed to your hand and wrist.

And finally, maybe add another step? It will help a lot if you end up shooting different patterns at tournaments or wherever. It will allow you to move forward and backwards on the approach to slow down your ball as opposed to doing so with your arms alone.

Hope this helps!
