Visited! To put into words what is the most beautiful part of your town I shall reply in story of my time there. I hope you don't mind me adding more than one photo. I just can't help it.
First thing when visiting your town, its so beautiful! The amount of hybirds and flowers its just...wow beautiful. Must of taken you a lot time to get all those flowers. Along with the amount of bushes and placement haha.
After admiring the scenery I went into your main player's (mayor) house. The first thing I notice is your furniture is refurnished into the design of the Animal Crossing 3DS XL. Nice touch!
Now at the basement I found your cafe. It was odd for me to see your cafe in your basement, not sure why. I guess I am use to players not commonly putting it in the top floor or basement. But I can see why you have put it there sort of. Its a very lovely cafe, with using 7 - 11 items and Brewster gyroids at work, I love it haha.
Went into your other rooms see your bathroom, kitchen, pic room and etc. I also with visiting your other house.
Visiting your other villagers, Marshal had the best wave goodbye ever. You can really see it. Didn't know Marshal had a lot of sloppy items! Haha he is so cute.
Now to sum it up. The most beautiful part of your town is hard to determent. In my view all these item pieces and what have other members have posted (couldn't find that pitfall haha). All these bits make your town more beautiful than just picking one spot. I know that sounds a bit corny but that's my honest opinion really! Adding them bits all up makes your town so beautiful!
I can't just pick one! (btw: I think Marshal is stalking me...your main player was too. Kept running up to my face haha.).
