Alot of people do make errors while making cliffs, especially when they have sand at the bottom. I notice people using the wrong two tiles for the cliff -to- sand at the bottom of a south-cliff... I also notice that within the cliffs, there are often specks of light colour, people cant find the tiles to fix that, so maybe You could do a part on cliffs...

Another thing that surprises me, is that many people have no idea how to do TREES @_@;
