I wasn't around then, but looking at old cartos rev 8 really stands out to me. It's obviously custom, but it flows really well together and looks like a real-life landscape for the most part. It's not so jaw-dropping that you don't want to destroy it's natural beauty, but it's not boring and repetitive like vanilla either.
The best word I can think of to describe the look of it is 'subtle'. And I think that's a very, very good thing.
