IWANNAGOFAST, that's really great. Did you make any of the loose rocks too? I ask because the triangular one behind the orange fish and striped fish matches the background color perfectly. very good color, too! On my next ones I'm going to do much darker rocks - in the 29s I was matching light cream color real rocks I especially liked, but the fish looked washed out in front of the background - that was something I hadn't considered.
AquaStudent - I was going to suggest you combine the fallen rock/caves and arches, but now you have me curious! You'll have to spill the beans on your idea, y'know
