I'll Chime in on this one:
Couple things to add here. First and Jordan hit it on the head, mellow out your approach a bit, at least while your learning them. I taking a rage approach at mine but I did't learn them that way. Adding to this, in slow mo you can see that your not really doing a toeside trip, instead your using you momentum from the approach and pointing your head. What you really want is a toeside trip edge flip. A ts front roll, a crow, crowmobe, totsie, dum dum, etc all use a trip style edge, really it's exactly the opposite of a tantrum trip. You want to almost be changing edges at the top of the wake this will pop you straight up instead of out, create less line tension and make the rotation and landing easier. Here's a video of Colin Ryan, he has a textbook TS Trip. At the 30 mark you can see him push the board into the wake and he is actually leaving the wake on his heels. A few tricks later he does a TS Indy Front roll with same edge. Overall, I think this will really help you, more than anything the your video looks a little under rotated, causing your to not be perfectly square when you land.

Jordan and I will differ a bit here, in that I don't typically teach the two handed Crowmobe, I think they are ugly and its a super hard habit to break. Now what it does allow you to do is muscle and power them around, and it does help some people. I learned them this way and it took me forever to break the habit and learn it with a grab, almost had to relearn the whole trick. But everyones learning curve is different and it might help you.
Lastly is the blind landing, make sure you spot that landing early. I spot mine at the crow mark in the trick then keep rotating to blind. Once I spot that wake I keep my eyes glue to is to make sure my body gets around. Once you pass the Crow mark, you have to keep that handle in tight so you can get it into the small of your back. Keeping the rope in will help square you up so that you body is chest over toes and you can ride away.
Hope this helps and makes sense.
