The following is not so much a review as just whatever comes to mind.
My first thought is I was never quite fond of paths touching or being laid over (especially when only partially) the natural rock pavement of the plaza and other areas.
I tried being content with the Zen sand garden placement in my town, but never could get over how out of place it always felt for some reason. In your town, the garden is surrounded by bushes, flowers, a rock, and trees that, taken together, give an assymetrical feel; i.e., they are not intended to match or otherwise align with the garden. I wonder how that might feel in real life. Maybe I would find it most relaxing anyway.
Ironically, the only time I liked the garden placement was in a town dominated by cement and modern everywhere, so it felt more like an urban forest rather than a natural setting. And of course, it was the centerpiece of a particular area of town, equal square spacing of path surrounding it on each side, and I believe the city hall above it a few squares back. In other words, the garden was highlighted or emphasized with great care, rather than seeming incidental in an area so overloaded with details that you cannot really focus on the garden.
As I pass the fountain, another strange aesthetic issue I cannot get over comes to mind: paths that seemingly not only touch the edge of the river, but slightly go over it, which helps emphasize the artificial nature of the path in my mind.
The part of town with the hammock, fire pit, and spring feels like a museum of public works projects rather than something with a unifying purpose. What I gathered is you may have envisioned people sitting down on the stumps or the hammock next to the fire pit, and having a spring near by for even more relaxation, but it feels like a miniature park that was not planned so much as thrown together with haste.
Relatedly, I believe the reviewer above may have been hinting at this, as s/he seemed concerned about the reasoning behind a lot of your placements. I would add that having one or two major projects act as centerpieces for natural surroundings might make it appeal more, and feel more natural even though it is obviously planned. This seems ironic, but for example you might have a trellis with a path running through it vertically, bushes nearly surrounding it (except with entrance/exit in the north/south), and flowers hemmed in by the bushes. Although clearly planned, such a feature would have strength of purpose, would emphasize nature even while drawing your attention to the trellis, and could clearly be imagined as a feature seen in real life.
Perhaps my favorite part of your town so far is the top-right because of the 'city walk' feel it gives with a path running through the caf?, Re-Tail, camp site, etc. all the way to the beach, and a bench surrounded by flowers (which in turn are surrounded by the path) below these buildings. I think a police station might also go well there.
I can see what you were going for with the set of projects including the toy tires, fountain, fairy tale bench, etc. Although this seems like an odd assortment of projects for a park, I can actually imagine being struck by such a park in real life, as if it were the work of a daring artist/architect. In other words, I can actually imagine kids enjoying this, except of course for the part about being next to an unguarded cliff, heh (extreme park!). And it does feel odd and strangely bare because it is hemmed in by the cliff on the right, rather than being in an area where it can be surrounded by groves on all sides (not a neat line of trees, mind you, but trees sprinkled here and there near the outskirts of the park to make it feel more 'natural.'
(Ah, you already built the police station. Never mind what I said above, then.)
Oh, man, big television screen next to a resident's home. Sorry... Phoebe. Look on the bright side: at least there is no volume (I think).
I hope you might forgive my stopping here; a bit tired. Ooh, the geyser just went off! Never did try building that yet. I do like it, though.
Anyways, thanks for sharing your town with me; enjoyed it.
