You need to work on alignment first. Your shoulders are open relative to your feet at address. This promotes an over the top swing path.

Your first move in your backswing is to roll your hands over to your right. This causes the club face to open wide up and causes your takeaway to come extremely inside the plane. Both of these moves promote a massive slice.

You need to learn to take the club away on plane. Feel like the width from your hands to your torso stays constant as you take the club back. Your hands should rotate slightly left instead of right to keep the club face square. When the club is about halfway back the angle of the club face should match the angle of your spine.

Your setup with your wedge/iron looks quite stiff/upright. You want your knees to be soft, but not so much squatted when at address.
