I had a look a couple of hours ago and didn't get the chance to write this up.
I like the overall general aesthetic of it and the paths are very cute. I agree with above, that I'm not the biggest fan of paths that incorporate rocks instead of moving around them, but that's personal preference and again, also hard to do sometimes. I also found it a little aesthetically displeasing that the paths come to a rough stop, instead of closing them off with two corner pieces, like a round the plaza for example. Which I know is sometimes a sacrifice you have to make unless you want to cover the entire plaza with pattern, but I found it a bit jarring. I like all the flowers, but I also agree with earlier comments, that it's a big disorganized on the color scheme front, which isn't necessarily a bad thing. I would just find it odd when walking by pink and white flowers to find a blue rose in the middle of them. I think a more "artfully cluttered" look would help with this, picking out a color that matches the scheme enough but is still a bit different and throwing a few in there. I liked the PWPs you had, but I think I feel like I'm missing trees? I think there's also more that can be done with the beach, but it's not that big of deal, so if you left it as is, I don't think it would detract from the town. I enjoyed the outside and even with the criticisms I have, I definitely loved the overall look and feel.
I do have to admit though, that I wasn't particularly impressed with interior design, which is fine since that's personal preference, I just thought the rooms were a bit lacking in the larger house and the two smaller houses are a bit hard to decorate because of their size. I do however love how they look on the outside with the town, so I think the two smaller houses are fine as is to keep the overall aesthetic outside.
We all make our towns how we like and I like that your town looks and feels different than other towns that I've been to. You did a really great job and should be proud of yourself!
