Okay. So I've noticed several err, and call for improvement that you needs.
1. Potted plants is not, and won't alway be the solution to emptiness of the building. If you abuses too many of these, people'll start to realize how truly empty the building can be if the plants got removed. Try, and shrink down the size of overall structure, or else suffer the consequences of having superly large spaces with nothing to fill in. This is also a suggestion to go, and experiment with tiles.
2. Always remember to do Generate Icon, in the dropbox. You'll find icons that you never knew existed, perhaps because it doesn't make it though the official loading, and was accidentally hidden because how terrible BYOND is.
3. You should, and NEVER cut off the carpet once it touches the wall. You must complete the carpet, and not look like it got cut off by some girl with gigantic scissor. Not only does it look weird in reality, but it feels like the carpet is just incomplete.
4. Never, and should I dare say, center the room. If you're making separated room, and rooms for bedroom for guests. You should never center the door, you should move the door to the side of the room, either on west, or east never the middle. This is so, you can place the bed where a bookcase can be on one side, and drawer on other instead of drawer on one side, across from that, separated by a door, a bookcase. Try, and consider the placement of the doors.
5. You should consider other tiles, before you do the tiles you've commonly used to seeing. There are chances that combination of certain tiles are much more sufficient, and cleaner compared to other tiles simply because that tileset have more variety, and more options compared to others.

Other than that. You know who I am. So that's enough said.
