This is my first scene that shows underwater, so any critiques would be helpful. Created and rendered in Blender 2.69, Cycles engine, post-pro in Paint.NET 4.0.3.
Very nice!
HOLY SMOKES!!! VERY NICE!!! 
Thank you!
:spin: You’re welcome! :eek:
Awesome work. I would love to know more about this, specifically how you approached the underwater shader and the “surface” between the two parts of the image.
Some clever faking, and a little magic 
Haha I get it. A magician never reveals his tricks. Well done anyway.
