Pics (SMALL!) look like good technique, but based on those three pics (definitely not enough info for this to be definitive) it looks to me that you, like a lot of people, are simply along for the ride in your carves. This seems to be common...put the board on edge and just follow. I'm no expert, and only a moderate level carver, and have definitely used this tactic before (and am not saying anything is necessarily wrong with it) but if you want to get into more advanced carving on steeper trails or variable terrain, you have to be more aggressive, take control instead of just letting it happen.
try to find some vids of advanced carvers and notice that their turns are pretty dynamic (har har! (inside joke on me)) with up/down movement, and aggressive turn initiation. Rarely do they just tilt the board and go along for the ride.
I think you look like you've already developed good habits as far as body positioning goes, now you just need to step it up a bit.
Since you know how you ride, does that sound accurate?
