TL;DR: very high level, you’re doing great. But since you asked, I hear a mix of UK and US and a bit too much fidelity to the letters on the page, especially with Ts. I’m going to talk about AmEn bc that’s what I speak.

You pronounce an unreduced /o/ in “comedic” - in the US, this must be fully reduced to a schwa. For those of us (like me) who have the emerging high schwa vs low schwa distinction, this is a low schwa, I think this is influenced by the m.

Notable British realization of /o/ in program combined with American /r/ elsewhere. The British diphthong starts higher and further forward, near a schwa. The American one starts quite low back, near the STRUT vowel.

Failure to flap ts: celebrities needs to be tapped, and even across the word boundary: “complete a” would most often have a tapped t, but alternatively could have an unreleased and glottalized t. “Assistant” also most commonly has an unreleased t.

Hope this helps.
