I'm visiting your town right now, so I will right this as I go.
First of all, I really like the cedar trees around the plaza as well as the patterns.
However, I think the area around Prince's house looks a bit cluttered with all the flowers. I think you should clear the area and then line the house in white violets, and then place bushes and trees around it. Over all, that area is very empty.
I also feel like the park area would look better without the flowers. The flowers you have clash with each other and it distracts from the pwp. I think the area would look fine with no flowers. The patterns are nice though. I like the checkered pattern you have going on.
Also, by the stone tablet I think it would look better with just purple pansies.
The area by Marina's house is cute, but it would look better with just pink flowers. Like all pink roses or all pink lillies. And then towards the flower arch, maybe take away those flowers there, or arrange them differently. In the space between the bushes and the peach and cherry tree, I think you should do pink and white cosmos alternating. And then clear the space where you walk.
Again, by Parfait's house, I think it should be yellow and pink lillies together. The other flowers, while the same colors, kind of throw thr scene off with their different shapes.
Most of the things in your town are very cute, and I like it a lot. I just think the random flowers mixed together are what is throwing everything off. In my opinion, putting groups of different flowers together just kind of makes things clash a little bit. What you have is still cute though, and I like it a lot. That's just my preference with the flowers though.
I think orange cosmos would look nice around Fauna's house. The black flowers are nice, but with her bright roof it kind of feels like they throw it off a little bit. I also feel like the one bamboo stalk in front of the bench kind of blocks it
I think Marshal's house would look good lined with white carnations. The purple and white pansies are cute too though, but I'm just thinking since his house is white and so is he maybe the white carnations alone would look better?
I think you should remove the red roses by Tom's house and just have the blue ones. Again for the bottom, along the cliff. The red and blue are both so bright and they just don't match each other or the area. Blue alone, or blue and white would look better.
I like the pears around your town hall. I also like the blue and purple.
The purple and white around the windmill look a little weird to me though. I feel like maybe a darker color would work better here?
Also, really like the space around Clyde's house. Yellow and orange look good around his house, along with the lemons and oranges. If you wanted to, I think the area would look fine with just the yellow and orange tulips.
Over all, your town is really cute. I just think the flowers are what is throwing it all off. I think if you take different color flowers of the same species and lined them up like you have now, or changed the colors in different placed that it could make the areas look better. That is just my preference though. What you have is really nice though.
