you can try to use a dark blue or black as the first layer of water then go over it with a lighter blue and add some highlights to it. i like the way that the sky looks except the clouds are to dark and looks about the same. you can try to use more white and then darken it with the color of the sun.
First of all, great stuff! I think mood is always 80% of a piece, and these are both moody.
I definitely agree about the values of the tower and their relationship to their distance away from us. I think the top image needs a bit of atmosphere to set the distance.
The bottom image in particular is awesome. You mention unfinished highlights- I hope you're not adding too much, as right now I think the light is working almost just right as far as value. Maybe add some highlights here and there, but its murky and kewl right now, too.
The only thing I might suggest about that bottom image is about the ocean surface. We can see the moonlight defining the ocean surface for us, whic works really well. But I think maybe its a little limited in scope. Those cool, destroyed buildings that you suggest seem to kind of trap the 'surface glow' to that one area. Think about subtly extending that glow behind those buildings a bit. It wouldn't take much, just a hint and suddenly the scale of the scene opens up.
As for the contrast on the building i agree. originally it was a much darker slick black tower but the director wanted it to be made of white ivory or marble. I guess something went wrong along the way. I'll try and fix that. not really sure how tho...
I'm not really sure what you meant by everything looking the same but I guess the sky does lack some depth/dynamic feeling. will try and fix that. Also will try and make the moon look like a moon and not like a sun
im glad the mood comes across.
I get what you're saying about the surface glow. Will do.
I won't go overboard with the highlights. Just meant to point out that i havent applied them yet. Nor any of the bounces from the red neon light.
