I do like these. The only real "issue" I have is that I wish the moss was in a darker green but, other than that, I remember I really liked pretty much everything else when I tested. Specially in the below example, which DY pointed out, the improvement is, I think, rather apparent. I remember in one of Bethesda's CK tutorial videos the guy who was presenting said that rubble was the most widely used resource in Skyrim (or something along those lines) and the original really looks terrible when compared to amb's.
