@TheOne: You're right of course, but getting really perfect results in TG2 is hard enough already. The difference in height is easy to do, I'll give that a go. The ferns can be modified as well, but in the top picture I used a different image map compared to the latter iterations. It was more uniformly (too dark) green at first. I threw some tiny fractals over it, but maybe not enough still.
I added some fields, but I don't know about it. too much going on now, IMO. I also added some dead moss, but forgot to turn of displacement, so it's all too rough now. I need to redo the moss stuff.
