Its not horrible, but,
1. I don't know of any (normal) people that would want to live, eat and sleep in a place with that many windows.
2. Where does the fridge door go when you open it?
Things you did well:
1. Its not only 5 bricks high.
2. It's not in space
Things you should improve:
1. It needs to be at least twice as big. I know its a small house but its like twice the size of the outhouse. You don't necessarily have to add more stuff inside, its just all so cramped.
2. Never ever have the outside wall be the inside wall.
3. There is a lot of flat space, change it up a little, get creative.
Overall it doesn't make my eyes bleed like a lot of other builds recently. You've got a good start, just keep working on it!
