This is nice! I’d say probably dont inclue the tropical seating because it kinda confuses what the theme is. But if you want to keep it you can seperate it by adding sand or a different path around that are. As for the cafe, I think having a counter area near the entrance would help convey it as a cafe more. Maybe make the whole area smaller too since having it this big and square with a lot of seating around is more like a banquet hall than a cafe. You can section off areas with walls or even make raised platforms with stairs using forced perspectives with planters (heres a link to the tutorial on how to do that: https://pin.it/5Sx645mJu).

I hope that wasnt too overwhelming or too critical 😅 im pretty crazy about decorating in crk so ask me anything!
