The characters and background look great, especially the effects of the flare. I'm a little perplexed by the tank though, its got this gothic/Giger thing going on that looks out of place next to the more Killzone-esque soldiers. The treads also seem to dissappear above the front roller, and there looks to be a piece of wood floating inside the suspension but that's just nitpicking.

Great Painting.
I had an idea to do a similar drawing once and it turned out terrible.
You nailed it, awesome illustration and lightning.
