Instead of checking the whole way down just ride normal then a stop few turns above your straight line point. From there, point it (this should give you enough room for a correction or two as needed).
That jumps isn't so hateful if you knuckle it. Change your stop point higher and higher as you need to. Really would want to get comfortable riding straight at the jump and judging what speed you actually need. This will allow you to focus more on eliminating your body's natural "fear lean".
The biggest key to jumps i've learned is to come in loose and light on your feet. The more you tense up in anticipation of the ramp, the more likely you are to lean.
In all though it looks good. Keep at it!
