Why is it so cold? Other than the guy's white hand (and if it's that white from
cold, he/she is dead :*) I don't see it. Nice rippling on the water, and
interesting floor.

The hand doesn't look as bad as you say it does and the fish looks good for 
it's simplicity.  The angle is the key, if we could see the side of the fish 
it would suffer.  The refraction of the tiles through the water is great.

From bsieker@techfak.uni-bielefeld.de:
If the tiles disappeared when the IOR was too big then probably the plane has
the normal faced the wrong direction (i. e. downwards) and you suffer from
total reflection. If it were pointing up the water would correctly simulate
water and the tiles would remain visible at all angles.
The hand is quite good.

Nice concept and composition. Lack something more playing with refl/refr.

Skin texture is difficult to make, isn't it?  I found this out myself.
