Beautiful love the concept and the overall design came out great. the only thing I have a problem with is the lack of contrast. Try adding some darker tones here and there to really get across the setting light mood.
I love the shading and scale of the machines. The smoke billowing into the sky is cool effect and those piercing blue lights really capture my attention. Very War of the Worlds! I think this looks like a job for one god's humblest creatures...the Tyrannosaurus Rex![link]
