Honest opinion

[outtafocus]

Thanks for all of your opinions!
Im surprised I got a lot more thumbs up than I expected. One of my plans is to try and hide the powerheads behind some rock, I would also like a more cave like portion.
I will play a little more with the structure when I get the chance. It seems that every time I go to move a rock, my emerald crab just happens to be clinging to that exact piece, and I am always affraid of squashing him.
