Wings.

Yes the whole shark thing may lead to some different underwater type 
scenes to examine the associated lighting/media/refraction issues.  This 
really started out as a modelling/texturing study, lol.  I thought the 
shark shape would be relatively easy.  But like any simple looking 
smooth form, the subtlties become more important.  The setting is still 
not all that convincing but it is better than the last 35 or so tests 
that I have run. As I meantioned the clearer, darker, totally camera-lit 
renders ( and reference photos ) tend to look prettier, more colorful, 
more contrasty. But the more turgid looking, filtered light seems much 
more of a challenge.
