Even just looking at the pictures, the thing that stands out is how much everything blends together. I’d suggest texturing the furniture and possibly walls. Given that (at the moment) roblox textures are fairly limited, I’d recommend looking up “Texture” in the toolbox and using some from one of the many free texture packs. (Right-click, “select children”, copy, paste into the part you want it on.) Overall it looks pretty good for a first attempt at building a house.
Alternatively, slight differences in colors between certain parts could also help, especially the couch cushions, to give your detailing more definition.
I like it! Especially for a first house! I can say this is much better than first house.
There are a few things you could change about it, however.
I would suggest removing/shortening the wall dividing the living room. It’s way too short and needs to give the room more space. Move the plant and sidetable + lamp to the wall on the left of the picture or move it next to the TV.
The barstools are way too high, i’d recommend lowering them.
The upstairs needs railings next to the stairs and possibly a different floor color, im not loving it. Maybe you could add carpet in the bedrooms and leave woodfloors in the hallway
The terrain is pretty bland, though that’s not what I’m here to comment on, you could pretty it up a bit.
You should add ceiling lights, right now the only source of light is coming from the lamps placed around. Maybe you could also add little counter lights under the cabinets in the kitchen.
I think the porch could be stretched further up, it’s kinda small right now.
There are other little things I could comment on, but for now I think that’s enough.
I really like it, it kinda gave me old roblox vibes. Nice work!
