Nice! although i would recommend getting a plugin called “Part to Terrain” and turn the grass into a terrain then head to terrain in Workspace and turn on “Decoration”
also the skybox needs more clouds and if you havent already, head to lighting and switch Technology to Future (or Keep it at shadowmap)
other than that, good build!
plugin: Part to Terrain - Roblox
Edit: Also head to lighting and add a bloomeffect, mess around with the variables inside till you get a good glow from the lights. (also i just noticed your ground is terrain, so try heading to file-studio settings-render-edit quality level and change it to above 3 at least)
LOL i did use part to terrain and the decoration is on plot twist
When the road snaps in a different angle i reccomend curving it a little, it seems odd. 
still learning blender to do em
Looks good! the only thing I would say is to use some better trees, As I think those are overused, and generally don’t look the best. (this is completely up to you of course) I wish you the best of luck with this!
