Hard to say from a face on view, but even with a lob wedge, are those clubs too short for you? How tall are you?
It looks to me that you stand very upright and don't have much bend from the hips or knees, which could explain why it looks like the club is too short for you.
Do you have any down the line?
I'm 186cm so that's around 6 foot 1 in the old money. Irons are half an inch over standard length.
Will post up some down the line snapshots when i get home
another big thing is watch in the clip where your head is at address and how much it raises in the backswing, when you come off the ball like that you have to make up for being farther away from the ball by releasing it early other wise you would top it so just concentrate on staying down throughout your backswing and you should be able to sustain that angle better and hit more crisp shots.
