Report him to Customer Service. It’s against the TOS to use reviews as leverage in negotiation.
If you did the job exactly as your gig promised, then he has no reason to cancel. Not liking what he got is not a valid reason to cancel.
It depends on how much you fear his bad review. If you really can’t stand to get a bad review then agree to cancel and if not then don’t. Since it’s your first order then cancel.
Based on what you said you should cancel it.
