Along with everyone else I want to congratulate you on a job well done. I like the brown as it reminds me of it having been a standard color choice back in the 1940's and 50's. As it happens I'm also in the middle of a build ("kindalikeawhizzer") which is being painted brown and cream. And like yours it utilizes a copper exhaust, also flowing straight back. The brown and copper compliment each other, I think.
How does it run? Are you having fun?
...and welcome to the forum!
