Tossing arm

I’ve watched TikTok’s and videos on serving and specifically what to do with the tossing arm.

My tossing arm is so awkward. I do the usual motion of maintaining the tossing arm while in trophy position or during the pendulum swing. But when I’m about to hit the ball, I move my tossing arm to the side while it’s still straight and it looks so awkward. Serve still works but looking back on videos and pictures, my finishing position looks really bad hahaha.

What do you guys do with your tossing arm during the service contact point?
