    I've noticed that too a little bit. My whole motion seems to be leaning to the left, with my body leaning left at contact and the ball not right over my head like the earlier Federer pictures in this thread, but to the right more. I've been trying to fix this (the contact, not the recovery), but I just have no idea where to start. Do I start with the follow through and recovery and just try to force myself more into the court?

    I'd toss about 2" to the right more, and drive into the court directly at your target.
    Best recovery is to stand facing the opponent, split step, feet wide, ready for any possible return, even if you had planned on hitting an ace.

    I would try to get the shoulder's turned earlier and much more. You are facing the opponent on almost every shot.
    You're casual, for sure, but the shoulder turn is the most important part of hitting.

    Also some slow motion serves from today:

    https://www.youtube.com/watch?v=wfzgOeJRHoU

    The resolution is pretty low since it's at 240 frames per second, but I think you can see my feet pretty clearly and how I tried to force myself to not fall to the left when I came down on the serve.

    Better balance.
    BUT, do you want an easy 5mph more speed on the ball?
    Try driving into the court. Right now, you're barely landing 5" inside the baseline. Every big server lands a full 18" inside the baseline, some more.
    BUT, if you want to land ready to defend your baseline, your drive into the court is plenty adaquate.
    Me, I hope my serve illicits a weak high return, so I need to drive into the court more distance, ready position maybe 4' inside the baseline.
    On second serves, I don't drive my body forwards nearly as much, but maybe just a foot to 18" inside the baseline for hard second serves.
    If you are happy with your current serve speed, do as you do.

    The video seems to be too bright and washed out. Was it overcast? Have you made any adjustments? Say to the E setting which might brighten the video? I'm not sure if the E adjustment functions in high speed video mode. Or any adjustments by using some other Youtube capability that I am not familiar with?

    The very irregular background with the trees behind the racket is not very good. How is the background in the other direction? Maybe a sky background would work better for showing the racket? I found that a very dark tree line worked well but it was just a very even dark background.

    Suggest getting a video of only the upper half of your body to above the racket. Have the camera look directly along the ball's trajectory - toward the deuce court when serving to the deuce court, etc.

    If you do not have a tripod to hold the camera closer you might use a small step ladder. Drill a hole in a small piece of plywood and use a short 1/4 -20 machine screw to attach the camera. Clamp the plywood to the upper step. Better yet you can rig almost anything with c-clamps or strong spring clamps (Pony) etc. and a few pieces of wood screwed together to form two right angles.

    The camera has to be focused on a high contrast object the same distance away as the server. One way to focus is to point the camera down at the baseline and press the still shutter button 1/2 way down. See instruction manual for focusing.

    The good news is that your racket can be seen with small enough motion blur to see how it is facing.

    Serves from today, I definitely got more power the more I tried to force myself into the court, but I couldn't direct the ball hardly at all. It was going all over the place.

    Much better, and good ready position!
    Anything worth acquiring, it worth the effort needed to acquire it.
    You would need more than a month of practice, using the new forward leg drive, before it becomes anything approaching the consistency you have now.
    Pros practice their serves. Well, it took them 15 years to become pro, and they were practicing their serves. They all STILL practice their serves.

    OK, I'll take your word for it. Is there anything else technique-wise on the serve that I should change, or does it look good enough now that I should just work on practicing it?

    Compare frames of your video to these frames showing internal shoulder rotation. At 240 fps there are 4 frames. Impact is not included in the 4 frames below.

    I can see that your wrist might(?) have a more stressful angle than Federer's and other high level servers.

    To extract frames from your video you might use the Windows 7 "Snipping Tool". To post frames first use the Snipping Tool on a stopped frame and save the picture to your computer. Upload the picture to a free photo hosting site such a Snapfish or Tinypics. After uploading to the site right click on the picture and select "copy image location".

    Then, while composing a TW reply, use the icon above the TW reply text box - looks like yellow sky, mountains & sun? - for posting pictures. Click it and paste in the image address location from the "copy image location" step above.

    Compare your frames to Federer's.

    Don't draw conclusions until you can compare the same angles from the same camera views.
