There's so many elements in that iceberg picture, but the first impression that remains the main one, is a giant hooded troll giving me the finger! LOL Love the reflection on water too!

Lau...lita, ;), at least for me, the 'trick" to do an iceberg that looks real, is to make a mountain, and then, in edit mode, paint it almost full (but not quite), and then add spikes and mounds to it... I don't know if Bryce does it the same way, but it would be fun to know?
