Well, I was tempted to leave it as is and concentrate on other things, but I couldn't resist a little tweak

(heh, not so little a twaek as I've actually spent longer on this than I should have done... though most of that time was test renders etc)
Anyhoo here it is... comments / crits are more than welcome though I gotta start concentrating on other things now so I shall probably call it finished.
There is raytrace on the water (sadly no antialiasing or refraction as that takes it way over the 3 minute mark.) But to cover up the jaggedy edges I managed to squeeze in some volume fog (I'd like it to be a little thicker and have more wispy tendrils... but again limits limits limits!)
Render time = 2:58 Phew!
