Video and riding are looking solid Audrey! Just a few small things I noticed that may make a difference:
The jumps in which you came up short and landed on the crest of the 2nd wake from either heelside or toeside are largely due to reaching for that grab early. You've definitely got the "bring the board to you" part of the grabs dialed, but if you wait just a touch longer till your approaching the apex of your jump (in the air obviously) before bringing the board up after standing tall at the wake, you'll get the full POP from the wake. In a lot of your grabs, the board starts coming up right as you get to the top of the wake, and you're absorbing the wake to a degree. I noticed with your 180's you clear the wake with plenty of room to go, even a couple into the flats (YEAHHHH!) and that's due to you keeping your legs straight all the way through the pop as you're not adding the grab, and the extra pop is definitely showing! In picture 1, you're on edge, spot on. In picture 2, your starting to get those legs straight to get that big pop. But, picture three, you're legs are bent again to prep reaching for that grab, so you missed out on a lot of the pop. Picture 4 is the take-off for one of your 180's and you can see that extra bit of straightness in your legs, and that little bit can make the difference! That 180 you cleared the wake no problem. Just a little bit of a timing change there and your grabs will float down the other side of the wake like buttah!
Sorry... that one kinda got away from me!
Other thing I saw, you've got your grabs and 180s very consistent in your ability to land them, from BOTH sides. If you keep that handle a little closer on the 180's, you could VERY EASILY add any number of your grabs in there for a super legit grab 180. You've got both pieces, time to put 'em together!
All in all, great video, solid foundation, and great riding! Keep it up!!
