Hello! I'm currently dreaming of Vanille right now! I'm not super knowledgeable on dream towns, I'm only saying this on my personal esthetic - what I would do were it my town.
You've got a great start! I know you probably have big plans, but are waiting to get them out. For instance, I knew what I wanted, but I had to wait for the funds, and more specifically, the villagers to suggest the PWPs in the first place. So I'll say I like the direction Vanille is going.
I would add my third bridge by Freya's house, to make checking the campsite easier. Also, I wish I had built up my campsite more, so I'd add the firepit and log on one side, the chair and cot on the other, maybe the hammock near the clump of fir trees to the left. Then I'd add more fir trees and holly bushes in that area to make it feel more woodsy. Also, I'd lay a path to it (even a dirt path - if you're not up making your own I saw a qr code one once.
I like the shrub lined paths. I also know how time consuming and tedios that is (currently doing something similar myself). It looks really classy. I also like the pathing you chose. For me, I'd leave the plaza naked just because it's a pain to refill the tiles after an event or Redd comes to town (I can see the outline of his tent).
I'm interested to see what you do with the big area between Sydney and Marshall's houses and the river. With that much open space, I might do a playground - jungle gym, tires, sandbox, etc - or maybe a mini monument tour. I like where your coffee shop is, and police station. Overall it looks pretty good, lot of potential for some creative ideas.
My dream address is in my sig. Playing around with my town (ignore the complete disater that is Jane's messy house, I needed her inventory space briefly and forgot put it back. I'm on that soon... Also I just got rid of a PWP and have space for one more, though which one? I'm open to suggestions!
