Did you just clear coat it? I like how you left the brazing show. Makes it stand out that it's steel. However I'd be wishing that steels natural color was bright tangerine orange, bright blue or other bright color.
I wonder what kind of anodizing or some other chemical/electrical process would be possible to change the color of the frame and still let one see that it's a bare frame with no paint?
Maybe on your next build you can get that figured out for us.
But good job. Enjoy it.
