Hello!
If you can give the name of the reference or provide a link that would help a lot.
Both builds look fine, but heres a bit of feedback
For both builds add slight color variation, everything just looks one tone and it doesn’t highlight any sort of depth and dimension.
The builds look like they were just powerwashed.
The roofs look okay, perhaps add some more depth and detail to the middle of the triangle because it looks empty. I could also purpose adding shingles to the roof because it looks so flat.
The columns don’t look very column-y, add more depth and detail to them.
Otherwise the build looks good even without those changes, if this is more of a scenery build then it can be left as is.
