Wow. Excellent job, and I'd say that you hit you're goal.
I like that seat. It looks to be more comfortable than most cafe seats I see. The curves of the tank seem to match well with the curves of the tank. The green frame is a bold choice, but the color is not so bold as to dominate. Nice chrome.
Someday, in this lifetime, I hope to say, "Time to move onto another project." ;-)
