Thanks guys, this one was not easy. When I tried to take down the colour of the sky, it banded so badly on me that I had to find a way to totally generate one that would have the gradual transitions that I wanted to display without the banding and still not show where it had been brought in behind the A/C which I really didn't do too much to. The second prob was to try not to affect too much in the shape of the clouds while increasing their intensity and making them show as more menacing to the calm of the sky.......all the while, keeping the ASW 28 in its clean look and not having too much of sky or cloud manips spilling over and dirtying it...Darkening down the water effect was the easy part....all I did there was to add a whole bunch of fish and it easily became more opaque.......
