Handle looks a little out and you could let off your edge even more - 100% square up. You cut into the wake at the top does nothing for this trick, its all the momentum you carry from the first 15+ ft. you're cutting in with.
Not that mine are perfect - but take a look at the phot below and compare the following -
I'm a more squared up to the boat - going straight up and over my back (like hitting a curb of you're roller-blading backwards)
My arm/handle isn't 100% extended, I have some wiggle room there
I stay a little more tucked up (grabbing in this one) -- but even without a grab it I think this form makes it easier
-- hope some of this help!
