I like the content here quite a lot! You've conveyed a lot with nice voice. I think there are some mechanics you can clean up. First, I'd clean up the comma splice in the first sentence. You can replace it with an em-dash, a sentence break, or a semicolon (though the latter probably doesn't suit the voice).
More important, the pronoun antecedents in the third sentence are a little confusing:
"The forcefield had gotten
them back to the platform safely, of course, but something had kept
her from rejoining the bustling crowd of passers by, continuing
their journeys unfazed."
I think the first "them" refers to the jumper, but then I get pulled up completely by the "her". It has to refer to Bunmi -- there isn't anyone else it could be -- but the placement of the clause strongly suggests it's the jumper and not Bunmi who doesn't rejoin the crowd. It's just confusing. Finally, there's "their" but it has a different antecedent than the prior "them," which isn't ideal.
It might be that you are trying to cram too much into one sentence; give yourself a little more breathing room for all the ideas in the third sentence and see if it comes out smoother.
But again -- intriguing content and voice! I would read on for that.
