Animations flashing / Not loading properly

Hello!
I am having an issue with my animations, it seems to show the regular page (un-animated) a split second before the images load and it proceeds to animate as it should.

I have tried disabling the preloader, no luck.

Ideally I’d want nothing to render before the animations can be executed smoothly. Any help is greatly appreciated, this is my site: https://www.bravenewcreative.com

Thanks!
