Looks like it would have been an interesting piece. I know how it goes though. You have a great concept, but you abandon it when you get stuck on other ideas. Still liking the green tones and toxic look of it.
Hmm *reads over the comments* There have been quite a few dumb ones.
But who am I to talk? I like it and thats all that really matters I spose. Love the detailing of the rust. And I think this would be really awesome in oranges and reds... to really show off rusting and ugliness of some nuclear power plant thing.
