Welcome to the forum. That is a very nice swing. It has many of the elements of a good swing. I am not an instructor, but I will take a shot at a quick analysis.
Below is a screen shot of the top of your backswing, A4, and position A6 (downswing where the shaft is parallel to the ground). The red lines represent where your head and left hip were at address. As you can see, you get your weight forward very far. Maybe too far. Most people, including me have the opposite problem of not getting the weight far enough forward.
What this does is move the low point of your swing forward. It usually is where your left shoulder is at set up. The second screen shot shows A1, set up and A7 impact. The line is where the low point would be if you didn't move your head forward.
Because you have shifted forward, you are coming in a bit steeper at impact delofting the head and still swinging out at impact. This could cause the low hooks.
Check out Key #1 in the link below. You can also, for the meantime, just move the ball a bit more forward at set up. A good drill to practice is draw a line on the ground on grass as if it were a ball. Then make swings along that line and see where the divots start with respect to the line. If they are way in front of the line, then move the ball forward a bit and see how it affects your ball flight.

You have a very nice swing and not a lot to correct in my opinion.
