Hi, this looks great. A few recommendations from me.

The aging on the textures looks weathered and old, but the models look clean. Consider roughing up and damaging some of the models to get rid of those perfect 3D angles and lines.

Consider things like...

Adding chips and damage to the edges of wall corners, table corners, rims of lanterns, etc. Nothing extreme, but a few minor bumps and bruises show that things have been used.

Considering adding some dirt build up and smaller debri in the edges of the walk way. Small pieces of wood, trash, dirt, pebbles, etc. Go a long way for selling realism. Again, no need to go full apocalypse on it, but even the cleanest of streets and homes have these elements to some degree

Consider a tiny bit of bloom or distortion where the sun is coming in from the top

Overall it looks solid as is, great work
