Posting the side angle was helpful. Your toss looks to still be landing on the baseline, and you have little leg push as your forward foot doesn't even clear the ground on most serves.
You can work on both things separately before you combine them. First, I'd practice just with the toss and make certain that the ball is landing in front of the baseline. Next, I'd put something like a tennis ball lid in front of your left foot and then while hitting a relaxed serve, consciously hop over it and let the right leg kick back on the follow through. Don't worry about hitting hard, just try to get the hop to flow with the swing.
