I don't know how to do a method (that's my disclaimer for the day), but I'll comment on my observation of your video and the endless method videos I've already drooled over:
In those videos the back hand of the rider almost always comes forward, to counterbalance their bodies since they also bring their back leg forward. The back of your hand went up and stayed back (on the first video, couldn't tell on the second), which I think prevents you from really bringing the board forward to show the bottom and steeze out the trick like you want to. That's part of what makes you want to suck your legs back so quickly (on top of the fact that the airs are not too big), if you stay like that you'll end up off balance.
Seems to me like right in the middle of a method the riders hand, torso, and feet make a C shape. You're kinda at a J shape.
I hope this crude observation is helpful.
