Any feedback plz, thanks.

Nice turn @nikvanstar!

Immediately noticeable is your back hand flailing behind you over the tail of the board like a loose ribbon in the wind.  This is the second most common mistake I see aspiring carvers making.  The hand position is an error in itself but more importantly, it's a symptom of a larger error: your rotation (hip and shoulder orientation).

So I recommend doing the "hand to knee drill".  Touch your front hand to your front knee on toeside and your back hand to your front knee on heelside.  This can be confusing at first, just remember that it's always the front knee and you'll figure out which hand to touch pretty quickly. 

This is going to put you in a better rotational position for each turn.  When your back hand is over the tail of your board your hips and shoulders are facing the toe edge.  This is what we call "the warrior position" because it's kind of like the yoga warrior 2 pose with the hips open and the hands over each end of the mat.  I also call it the "CASI robot stance" because that's what CASI teaches their students and their instructors.  It doesn't work well for posi-posi carving on anything steeper than green runs.

On heelside, when your back hand touches your front knee your hips and shoulders should be facing the front of the board.  On toeside, with the front hand touching thr front knee, your hips and shoulders should be in line with your front foot.  So between the two turns your hips and shoulders should remain within that range, from facing the nose to about 60 degrees toward the toeside (more like 35 degrees in hard boots).  In your videos, your hips and shoulders are often parallel to the toeside edge of your board, way out of the ideal range.

So think about facing the nose and generating that rotational movement from the hips.  Rotate from there slightly toward the toe edge for toeside turns, but just enough to lead your board into the turn, never all the way to face across the board.

Look at this photo.  Bro has rotated his hips to face the nose of the board.  His butt is over the tail of the board and his front hand is just above his front toes.  Try to mimic this position on heelside, if you're not compressed as much as he is then your back hand be be right at your front knee.  Touch it.  And then work on holding it through the turn for longer and longer periods.

Wow, seems like a great advice.

Nothing have to add at this moment.

Need to do the training the way you tell. Will try to figure it out.

Anyway there is no snow at this moment, but will try, when it will be possible.

Thanks, appreciate it.
