Narrow the grip, hammer the lats.
Keep your chest up and drive the elbows down, not just pulling with your arms.
The neutral close grip lets your elbows travel down in front of your body rather than out to the sides, which puts the lats through a longer range and a deeper stretch at the top than a wide bar allows. The biceps assist strongly in this palms-in position, letting you pull heavier on the cable stack. It earns its place as the pulldown variation for building lat thickness and for lifters who feel wide-grip work only in their arms.
Neither is better, they stretch and load the lats differently. The close neutral grip gives a bigger range of motion and a stronger pull, the wide grip changes the elbow path and hits the upper back more. Rotating both is the smart play.
A slight lean is fine, around 10 to 15 degrees, with the chest up. What you want to avoid is rocking backwards to heave the stack down, the torso angle should be set once and stay there for the whole set.
You are pulling with your hands instead of driving the elbows. Think about pulling your elbows down toward your hips and let the hands just hook the handle, the lats will take over almost immediately.
