cutting in hard (toeside) and trying to burry my nose in my right armpit.
That could be your problem right there. One really common bad habit people (myself included) develop is throwing the trick right off the wake without getting the upward pop first. Leave it later, and don't try to throw the flip and 180 in one. First the flip, then once that's started, the 180.
Just think POP, flip, 180.
Also one problem you could have is bringing the handle up to your head, trying to get your nose into your armpit. Really the handle should stay low and not go much higher than, say, your nipple line at most. A video would be more helpful though
