No Man's Land is a Tower Defense Strategy game. Command Steampunk armies and utilize tactics to fight off hordes of enemies. Go head to head with other players or enjoy the detail rich story-driven campaign. Fortify your defenses to protect your base while spawning epic units such as infantry, tanks, zeppelins, and mechs to vanquish your opponents. How long can you survive?

I think you should keep this dark atmosphere, but add some kind of shine, or maybe phong, in the shaders. Something to really compliment the textures/models. Could possibly be achieved by just adding a Normal Map to the textures. (I don't know how your shader engine works. xD)
Also needs a slight amount of bloom.
I think it would look absolutely perfect with that. Right now, it looks great but at the same time it also looks a bit cartoony and from all the concept artwork I don't think that's what you want to achieve...
Thanks for the suggestions, appreciate the feedback.
