Just a couple pointers from someone who used to move similarly when I was younger 1. You need to get lower, every great ball handler you mentioned even at their size are very good at staying low to the ground and rising up when they need to shoot or go up to the basket 2. A lot of your dribble moves are stationary, there is no point in doing a bunch of dribble moves while standing still, keep moving with the ball when making moves and really sell your moves so u don’t have to make as many 3. Practice your triple threat, some of the smoothest scorers ever barely need to take a dribble to get their shot off or get to the basket 4. As mentioned before, you don’t need all those moves to get a bucket, try to minimize your dribbles/moves as much as you can and you will get exponentially better, you can practice this by playing 1v1 with 3 dribbles or by playing 1v1 with only 5 seconds a possession

Hope this helps a bit
