Hey
@WinterCO this isn't looking bad - you are coordinated and balaced, and you follow technical checkpoints - positions, motion - with good accuracy. It's very possible you could improve significantly with repetition alone.
Howerver, to make things smoother and improve with more efficiency you can tweak some elements. I agree with suggestion to get rid of high toss and hitch in your windup. I'd also suggest to practice, as a drill, more abbreviated sequence:
- Some serves with trophy pose preset before toss;
- Copying
current Djokovic serve motion (very straight windup without a hitch with racquet hanging somewhere down):
You then will settle with some "your" serve, but that practice will get it more assebled and connected.
- Second suggested drill - some stepping serving, like Federer warmups. When you don't stick yourself to a place, but toss some balls quite casually and smoothly swing at them:
Or this drill:
You need to build in some general fluidity and feel comfortable starting up your serve rather than tensing up or feeling like a powerlifter.
- Last but not least. Keep in mind that hitting power serves you don's need to hit them square flat. Yes, flat contact will produce faster ball all other things being equal. But focusing too much on achieving exact orientation leads to tensing up, which hinders RHS. Get comfortable with putting some spin on all your serves - you will be able to apply most efficient across swing and to use spin in your favor (more side or more top depending on toss location and swingpath), yet produce big pace for your first serves.
I also vote against focusing on small things at this stage other than as markers. You notice them, you interpret them, but you don't try to fix them directly. Work on basics, fundamentals, get repetition in, make it smooth and comfortable to repeat with confidence.
