Your town is so colorful! I love all the tulips around the topiary. I think you could surround the metal bench on the left side of town with bamboo so it's kind of enclosed. It would pull that area together I think. You could also plant some and then chop it down to mix it up.
The gold roses around the Egyptian pwp's are gorgeous!
I think the flower arch is misplaced. Maybe put it beside the police station near the bridge?
The area in the lower right would be perfect for the hammock pwp (near the bushes with mushrooms in between). And maybe a lawn chair or something.
Lastly, I think the space across from the police station could be used for perfect fruit trees. Not much room on that ledge, so trees could work well there.
You've got a fantastic town so far. I hope it grows even more beautiful!
