I’ve got your .blend and textures and It looks good! Some food for thought: The corner masonry is a little too flat / straight in the lo-poly. It will work out OK but a better option would be to go with the more irregular shapes like your arch stones. These kinds of old-world stones are hand-carved and look better when imperfect.
With regards to the arch stones they’re a bit hi-poly. I think the decimate modifier will take care of that well enough.
Lastly it would be more optimal for all the masonry objects to share a single texture, even a larger one like 2048 px. More numerous smaller textures is less optimal than fewer large textures. I will plan to combine UVs into a single 2048 texture at some point in the future.
You don’t need to make these changes but like I said, more food for thought in case you run into this kind of project in the future. Thanks for contributing to Collab2021! You’ve been a pleasure to work with 🤝
