2 and 3 are how I try to ski bumps (or at least used too). Can’t pick on any flaws which is kinda funny as I didn’t expect what I saw in 1.
1 on the other hand has issues that are well hidden because you are a strong skier and skiing on “soft” hard conditions. In order of cause to effect.....
1. You close you shoulders to the hill very early
2. This shifts your wt back towards the end of the turn loading your tails for transition energy or explosives release.
While this is fun and looks great, and does work well (given the conditions) it does give a wrong example and does cause problems as follows.
1. Early close besides shifting the wt back also shifts it in which under hard “ice” conditions can blow out the turn starting about mid turn.
2. This wt back is what I call bum steer and you can see you using yours. You can see in your tracks (in a few shots) how much you are loaded towards end of the turn. Again get into hard “ice” conditions and you are done for.
To be fair, it is good skiing and I suspect you where doing it to show off the skis and for the effect along with have the skill and knowledge to get away it and also when to change technique as required to suit conditions (2 and 3 bear proof to that), but since you asked......and people watch to learn be mind full of technique that sets them up to fail even if you can make it look (extremely) good and fun.
Sorry I was being nit picky.
