Things I love about my map:
Mostly horizontal river - it makes river fishing easy and doesn't take up a lot of space like winding rivers do.
All my main buildings - town hall, caf?, police station, and Retail all line up to make a convenient "Main Street" in the south half of town.
All my character houses line up to make a nice residential street in the north half of town.
The top left corner has just enough room for my campsite - it's a perfect secluded spot.
My beach is continuous, not broken in half like so many maps I see. It's great for ocean fishing and I still have a little private beach you can only reach by swimming to it.
I don't care about train station/town hall colors. I remodeled both to fairy tale so long ago I don't even remember the original colors! Brown maybe???
There are only two ponds, one right behind my mayor's house, which is cool (lake front property!!) and one to the right of retail. Ponds take up too much space so I wouldn't want more than two.
There are no rocks in the way of any of my paths. I was so lucky about this and my paths are set up so that my town is so easy to navigate.
Honestly, I've seen literally thousands of maps on here and I've never seen a town layout I like more than mine.
