The clouds are more clearly fake and the light shatters off point. This all adds to the effect that it is computer art. I also think in the bottom left hand corner is some of your most effective water as yet.

I agree, the attempt at clouds doesn't work for me either, looks more like scraps of torn paper than clouds.

It looks futuristic to me, and I realize I don't know much about lighting etc...but I like it

I like the water but not the clouds, a good attempt.

UHmmm same comment. when i looked at it to start with, looked only at the water and it looked like OH MY GOD, great great great. clouds need work, lighting is too brigh, if you "volume down" the lighting from the clouds you might pull of the lighting on the water...
very beautiful
