Looks great! The only thing I would've done different is used something other than cobblestone, maybe stone or stone brick. And I would've made the cobblestone part thinner with a little bit of grass around it, like grass on the side of a sidewalk. Maybe throw on some flowers and a couple trees on that sidewalk.

This is my first time uploading a screenshot, what do you think?
The beginning of the center of town.
But still, looks great! Good job!
