wow, it's looking good! You're going to fabricate a new roof for it?
How bout the slanted "pilars" at the front of the boiler on the sides..... should those be red too perhaps? I like your silver accents. I wonder how copper/gold might look. I also wonder if you might find a way to add rivets to the panel seems? Just food for thought. It looks good already!
Very awesome paint job on the metallic parts!
