Box cutter attempts

[Gnome]

I've been trying to land this one for a while. My kicks are kinda... low generally, my corks are alright although very hard to get a consistent perfect landing. I can sorta hyper although it looks ugly and I kind of almost sweep out of it. Here is the video of my box cutter:

So tips? Even tips on how to land a better hyper cork would be awesome. I really wanna nail this move cause I think it flows so well.
