I agree with Snowolf about using your board at more of an angle to start getting a feel for how it 'grabs' the snow. Right now you are going between slipping on your heel and toe edges instead of transitioning smoothly between turns.
The point that you are at in your progression is where I started to get more comfortable riding a little faster and realizing how much smoother it is to turn when you get some speed. Find a nice wide piste, get some speed and start making some really wide turns utilizing the tilt of your board.
I noticed you're also somewhat in the back seat, which is causing you to force the turns and sometimes go into whipping the board around with your back foot.
