Well the house looks pretty good on its own, but if I were to suggest anything I would say start by changing up the sides of the house and or the roof. Those two parts are pretty bland and no real detail. Same thing with the columns maybe add some sort of design. I would also suggest adding a background and maybe bring out the sides of the house to make it a more non geometrical shaped house. Could also add some shades in the windows for a bit of realism and the door could use some sort of door-nob or handle as well as a door bell. This kind of has a Halloween vibe so maybe like curved string with a spider at the end of it. Like I said at the start though its pretty good on its own. Good job mate
This thing looks awesome! But it’d be a improvement if you added something like a window on the second floor, or on the side of the house. Looked awesome still though!
