pretty cool. I'd add some shadows under the turtles and the crabs
(turtle) love is... giving crabs to someone you love
OH-OH...I knew this whole Turtle thing was trouble; No more animal or fish projects for me. Thanks for the heads-up Newsmaster.
If you were to take the bottom layer, copy it and put it on top, and make it very transparent, that would give a better underwater illusion, with the waving light lines in front of the objects. (In reality, the lines of light would change shape as they moved over three dimensional objects, but ain't nothing wrong with quick and dirty).
Sweasel. Where have you been hiding. I will go to my, limited, PS sandbox and try your suggestions. Thanks for the tip.
