The caves are cool! The blue one is a neat effect. The tank is turned up way too loud for me though. That bright sky is just too much.

The sky on the tank is pretty blown out. I was surprised to see any blue turn up to be honest. As to the caves, that's actually the way they are lit in that spot. It's real cool.
