I visited your town for the last 20 minutes or so. Because I can see that you're looking for(but unfortunately not receiving) a lot of feedback, this is going to be an extensive review. I'm gonna go over what my impressions were and give some suggestions, if that's ok. And if it's not, then I apologize in advance.
Ok, so first thing's first: as other people have mentioned, your tiles are mismatched. I won't go too much into that, except to say that the disjointed style is visually distracting from what seems to be a pretty decent town. I noticed that a few of the tiles were actually set properly. So I take it that you DO have the right patterns for them; you only need to fix them so that they're set correctly.
As far as your Studio Ghibli theme, I don't know much about Ghibli at all, and since I can't comment on anything in regards to that style, I'm going within the context of what I currently see, as it's presented:
Sakura's house is really nice! Visually, it's very cute and I love the wall/floor! I can't really say if you should match all three floors, if that's not they style you're going for, but I think the top and middle floors of this house are very good. The basement is good also, but the top two floors stand out to me more because they share a common theme.
Chihiro's house is really good and the setup is quite solid. It works well, and looks pretty cozy!
Kiki's house is cute! It's nicely put together and I love the patterns!
Satsuki's house is well very well done! I can't shake the feeling that it's incomplete, but given that I don't know much about studio Ghibli, this house is great! All of the rooms are cute and I love the customizations! I especially thought the basement was really nice!
Overall, with what's presented at face-value, your homes get a 10/10. Even though I know I'm missing a lot of the context with the Ghibli theme, what's presented is just so freaking cute and very well put together, and I'm sure the three smaller houses will be even better once expanded, if Satsuki's house is anything to go by.
As for the rest of your town, it looks to me like you have a few problems outside of the mismatched path patterns.
For one, your houses are built in challenging spots that seem hard for you to work around. Not saying it can't be done, just that you didn't really make it easy for yourself. For example, Sakura's house is built right in the middle of a semi-island, across the river from the villager Kiki. What would have made sense, is that a bridge would be directly in front of Sakura's house. But instead it's on the side in a very awkward position that's hard to work around, and her house abruptly appears when you cross the bridge. And because Kiki has her home in front of where a bridge should be, you can't place it there either. Villager home placement I can understand, because everyone has an issue with that, but you need to consider how your player homes are placed and what you can do to accentuate them, rather than have their locations drag down the overall aesthetic of your town.
Another thing, is that quite a few of your patterns aren't well placed, and I'm not talking about your path patterns, since you already know the problems with that. For example, the pattern around Sakura's house is kind of abrupt. Like bam! Out of nowhere, a pattern. Now, if that's how you want it, then it's fine. But as a visitor, it looks and feels very out of place. It's definitely a cute pattern, but you need to find a way to work it in, so that it adds to the style of your town.
Another thing is your flowers. Some of them are well arranged, but the rest could use a little more cohesion when it comes to their decoration. Now you DON'T have to do this, but I'm saying it since you're going for a themed town. The three things you want to keep in mind when it comes to flower arrangements for themed towns is style, color, and consistency. You don't have to have all three, but try to coordinate and mix them around to find what works for you. Going through your town, it looks like you started on those ideas in some areas(like the path area around Satsuki's house), but then eventually...you just gave up. Now if that's how you want your flowers arranged, then it's fine. But as a visitor, a lot of the row arrangements came off to me as disparate, uncoordinated, and kind of messy.
As for your pwp's, the placements aren't bad at all. But with the way your town is set up, they also feel very scant.
Overall, your town looked very incomplete. But that's not a bad thing at all! It just means that you have plenty of room to experiment and try new things! What I would suggest you do, since you're building your town around a very specific theme(Ghibli): visit towns that have the same, or similar theme as the one you want to use. Find out what worked for them, and adapt those concepts to your own style to build the town that you want.
DON'T COPY THEM OUTRIGHT. Adapt. In other words, take note of the ideas they put together, use them as examples to build your own personal style, and then create the town with the theme you chose using your own style and flair.
So that's my review of your town. Overall, I can definitely see the potential for your town, especially through the houses you put together. You just need to work at it and flesh out your ideas a little more.
