Modular Building

A modular building I'm working on, I am looking to add more variation to the different modular pieces specifically the pillars and the ornate pieces at the top to help break up the modularity.
I wanted to keep the polycount reasonable enough since this is for my third year project which is quite large-scale so optimisation is important, another priority for me was to try to make it as seamless as possible.
The architecture is a combination of Croatian with medieval Tudor, I used a lot of reference but looked specifically at different cathedrals in Dubrovnik for most of the architectural features.
These renders are all in Marmoset and I've included a little breakdown at the end :)
