I think it looks nice, and the size looks fine too, like the shapes, lights. The textures also fit nicely together !

Tad blocky for my tastes. Lower grid sizes to make some finer brushwork in spots would have been nice. Those protruding wooden beams for instance. Maybe some hanging Ivy models?

But needs a few more props added into the map and some more pronounced displacements used on the grass texture there, Interior is just a bit to dark for my liking. just a slight increase in there and maybe a lower lightmap settings to make the shadows more crisp wouldn't have been a bad idea.

Lastly, the high block walls surrounding the map are, well. Bad to be blunt, Should remove them and add in some more buildings to be blocking the play area and a 3d skybox perhaps. Can never hurt to have them.
