I think it looks pretty good, especially for a first attempt. :) However, you will get much moe realistic water scenes by turning off the atmospheric effects, such as fog and haze. JUst set them at zero. Depending on the atmosphere, you might also want to go into the "sky and clouds" tab in the main menu at the top, and make sure the "fog in the sky" slider is also at zero. It seems the real trick to effective realism in underwater scenes is to adjust the Fade Out controls in conjunction with the clearness controls on your water material, which are found under the Transparency tab in the material editor. Hope this can help you some. Oh, by the way... welcome aboard! Cheers, Mike
