Alright, I've chosen to show my hatred in pictures instead.
I wouldn't say that I'm fully against ramp cliffs. But this build certainly doesn't improve how I view them.

Sofas that lacks legs and a reasonable shape. This shape is sometimes alright but would be better with prints.

Basic builds that shows the floor on the exterior. Makes the build striped.

Any sort of symmetric terrain. You see it got a stair pattern. Totally my nr1 hate.

Various colored flowers randomly spread across the grass.
If you want wild flowers just use 1-2 colors with maybe different kind of tinting.

Depressive striped wallpapers with dirty dark colors. No.

Stone walls with various of grey. Works sometimes, but usually uses too big range of grey.

Oriental random windows. JUST... NEVER... DO IT

Fat stuffty roof. I think the inside of the roof should end where the wall end to look right.

This works sometimes but is not recommended to use.
