Fastball (what would you say speed is)

Breaking ball

Overall, not bad. I like that you get some drive down the mound. The only criticism I’d have of that aspect is that you seem to have a hesitation during your drive phase that I’d try to smooth out. An analogy is we need your delivery to look like throttling up smoothly to maximum rather than going through a gearbox. Lots of energy is wasted in the gear changes. Does any of this make sense?
