1. Its very spammy, I would use larger bricks.
2. its one color. I assume your colorset has more than one type of brown.
3. No windows. They're no living in a box are they?
4. Furnature? you have a table, a candle, and two beds.

And why is there a [reserved] space? what are you reserving it for? you can add updated pics to the OP.
