Are they? One could argue that most of the UFO designs, and their base, are rather suboptimal.
While I would agree that your base elements are a little bit too organized (I think removing one cow would help, and not having all the empty food containers in the back row at the north wall, but more of a mix), I would not call them ugly.
I very much appreciate the work you are putting into the ubase map set either way. Thanks.
