Gives a nostalgic opinion in my opinion, because I used to join freebuilds and all that were there was that kind of build. I wouldn't be blunt and say "That looks bad" because who knows? Like everyone has said It's pretty bland in the color and shape department, and you could spruce it up a bit you know? Think about how an actual house looks like.
EDIT: kinda hard to give advice to someone who thinks it's okay to mess up servers with deliberate spam
