Your town feels bigger than mine
Two things can make a town look small (well, apart from your own impression because of familiarization)
1) The river. If it's straight you have two big expanses of land on either side.
If it is very curvy and with U-turns (like mine) you have more little nooks and crannies that give you the feeling it's smaller when it's really just divided differently.
2) The more you build or plant (trees) the less space is left. Suddenly it feels crammed.
I think the second could effect your town a bit.
The north part of your town is very big due to the position of your river.
But you divided it in smaller nooks with lots of bushes.
Directly south of your town gate is a lot of free space theoretically.
But you put many sign posts there and put paths that lead in narrow corners that leave only little squares of grass and flower fields in between. One very big field of flowers for example could make it look more spacious.
That doesn't mean it is not good the way it is though!
I love the look of your town, the patterns you used for the ground look really beautiful!
It gives a very tidy but cozy impression
Does it really matter that it looks smaller when it is beautiful?
The most spacious looking towns are the empty ones. When you just started playing, before you have built any public project.
It seems very spacious then, but it is also empty and boring.
I'd rather enjoy a town filled to the brim with beautiful flowers and interesting buildings
than a town that is big but empty!!!
