So I visited your town and as I am not very good at doing reviews I have just made some notes and things about my opinions on your town

Miami:
-To start off I think it would be good if you left some items by the tree as lots of people enjoy having different clothes to wear and things to play with while wondering around dream towns.
-As I was walking around I did notice a lot of items all over town, Like furniture and walls. If I was you I would just pick all these up and put them in storage or something

-Also I noticed that there were only paths in some areas, I would try to finish these paths off as I think towns look cool with finished paths.
-I liked how you have made a start placing bushes around paths, I think it would make your town look really good if you did this around more of the paths.
-You have lots of nice and cute villagers to talk to.
-There was lots of empty space that I would suggest maybe filling with PWPs or something.
-Also your current PWPs are good, You have a good range of them but I would maybe try to tie them together with a theme.
-As I was walking along your beach I noticed there is a small beach that is only accessible if you have a wet suit so I think it would be good if you left out a wet suit so people can access the beach and also do some swimming if they want to!

-I saw how you had some patterned tree stumps in the path, I think that looked quite cool and was something I haven't seen done before really.
Houses
Lucy's house was the first I visited, It was just an empty tent. This did make me think that this was probably just a new character but because you have her as a tent you could try and make the area around her a campsite area, Although this could be difficult because of space restrictions. So if not, Maybe try and think of something else to do with her house.
Levy's house was the next that I visited, I thought you had some good pieces in there but they could maybe have been tied together a bit better if you gave the rooms a theme or used more full sets? I thought the room upstairs was quite cool and could be made to look like a really cute little sewing/crafting room if you felt like it?
Lulu's house was the final house that I visited. I thought it was a cute thing to do having one of the houses as a bakery. I also thought the outdoorsy theme for it was really cool and if you got more pieces for the bakery then it would look even better.
Overall I thought Miami was a good town that has loads of potential

I hope this was useful!
