Looks good overall but still need to work on getting out over the left foot with your weight. Think more of pushing your body toward the pitcher as you swing. Notice how much your left foot is closer to the pitcher than your belt buckle at the point of impact. Ideally your belt will be over your left leg at impact.
Work on extending pivot leg sooner and stronger which will cause your stride to be longer to the plate. Reach back and arm motion looks good. Launch from the back foot and try to get a more active follow through to the plate.
Arm extension is good. Upper body turn is good also. Just need to launch a little more from back foot toward the pitcher and use the lower body a little more to power up the swing.
Looks pretty good. Note how the arms (especially the right arm) are not extended at the point of impact. Also note that the weight remains on the back leg (which is bent) through most of the swing.
Need to work on extending arms and transferring weight at point of impact to the left foot. Think of driving your body toward the pitcher through the swing.
Swing 2 was likely a curve ball or change up that dropped well below the bat. Use your eyes to follow and project any ball movement to meet it at the point of impact. Hitting a moving target means plotting an intercept course and adjusting along the way.
