Newly renovated soundproofing mistake

[Constantine Hatziioannou]

I just recently bought my first multifamily. It’s from 1900 so I gutted it to nothing and re-did everything but the exterior framing and floor joists. I am an owner occupied and I just rented it for the first time for great money, but I can hear every footstep. I used cellulose dense packed insulation and 5/8 drywall. The upstairs has the original pine flooring but I went over that with the stc rating underlayment and a vinyl plank flooring. I have everything brand new,but I can’t still hear every footstep. I can’t hear any tv or conversations. Is there anything I can do?
