BIPOC and diversity

[u/Awkward-Ad2224]

I'm totally new with reddit and writing. Please give me direction and advise. I have a BIPOC secondary character, Celeste, and I want to be respectful and realistic. Can you please tell me if the following passage is real/insulting/not there yet?

"But back at the table, no one had missed a thing. From the moment Vikram approached, Hal and Celeste had watched every beat of the exchange without even pretending to give privacy. Hal sat back with his arms crossed, smirk tugging at his mouth, watching like a man who already knew the spoilers and was just here for the bloopers.

Celeste leaned forward instead, elbows planted, chin cradled in her palms like a front-row seat to a K-drama. Her eyes sharp, tracking every glance, every ping-pong back and forth, sipping it all like tea she had no intention of keeping to herself later.

Together, they bore witness to every word, every smile, every subtle turn of power at the table, an audience of two, riveted.

Now, watching Vikram’s back as he walked away, Celeste couldn’t resist. “His back is even foineee!” She stated without lowering her voice, leaning off her seat and craning her neck to follow his form."

First glance, I think you are on the right track. I say this as a white man in America, so grain of salt and all that.  

The line about "tea she had no intention of keeping to herself" does, however, read a bit like an attempt at sounding Black. I would get a sensitivity reader who speaks AAVE natively, and can help you write more authentically.
