Hi !
I've been thinking quite a bit about floors (And telling myself that floors aren't meant to be customers. But that's beside the point). You asked for your floor tiles to cover only a portion of the floor real estate, and I'm currently wondering where it should go.
I still tried to tile the whole floor with your floor tiles just to see what would happen.
Here it is:

I don't think that it is too repetitive. Though it is a bit too noisy to fill the whole floor (which is fine since it's not it's goal :). This makes it hard to discern shapes that are placed on top (at least for me).
It's not actually an issue for interior floors to repeat: they usually have a motif irl. And besides, having some sort of distinguishable repeating pattern may help with image readability.
Anyways, I think I found it a job as the counter's floor:

Imo it fits quite well here. In addition, the floor transition is not to hard to create and is quite natural.
What do you think ? Is your floor happy here ? Should I place it somewhere else ?
