Reminds me of the combine citadel in Half-Life 2. The cloud work is absolutely great, but if the angle of the perspective was turned a few degrees of center it would be aloft less boring not that I don't like it its just it would be even better good work!
Nice but could always have room for improvement.
Very nice use of perspective although It hink you could have pushed your atmoshperic perspective just a tad stronger. Also throwing in the suggestion of an people moving about would have given it more life.
Yeah, I was thinking that as well, think it can be improved massively with a few more hours, but I'm on a tight deadline as is and this does well enough to set the look of the building for now :P
I'll upload a revised version once I've had a chance to go back to it. I also think it's a little too cool and desaturated, makes it look a little flat.
