Who built this ?

Well sir, I knew as soon as I laid eyes on this piece that it was from the Hellboy movie. You've captured the essence and the mood of the scene very well in this piece. I didn't realize, till later (when I first heard of Steampunk) how much this movie and the second one had such a Steampunk influence - which makes both movies that much cooler. The depth and lighting that you put into this image is outstanding, you have a great eye for detail. Job well done!
