Nice work jack! Here's some feedback:
Exteriors:
-The ivy seems a bit too disconnected and patchy. Usually you should work from the ground up and cover everything in a certain area.
-The stone mix on the side looks a bit too "blocky." I know this is confusing to here, but just focus on trying to make realistic patterns that show wear. Work from the corners out or bottom to top, and then randomize the middle a bit. Ask me in game to demonstrate if you need it.
Interiors:
-The interiors are too open and empty. You can use doors to separate the rooms in some cases, but it doesn't really work well here, just make walls.
-Add some variation to the furnishing. Three drawers in a row is a bit boring, and they should also be covered on the front.
-Don't mix thatch types.
-In most cases the workshop and store should be on the bottom floor. The living area (bedroom, kitchen, etc) should be on the second floor, and the attic should be used for storage.
For your next challenge, build a 2-3 story house in the style of /warp grassyvale. Good luck!
