@ Hetzen: that is actually a quite nice "sea test" 
 What are you planning to do with it? Use it for the NWDA image contest? 

Back to the canyon and rock surfaces from TU....  Quite a few people now have the pack, and to be really honest, I can't wait to see a couple renders from you guys published here! 
In a sense, such a preset really is like a child - as the father (in this case TU), you want to see it grow and live - if you know what I mean. So at least what I'm concerned, I can't wait to see your renders made with it! 

Cheers,
Frank
