Stan;
Looks like a good piece, to me! I like the chipped-off and (I guess it's "flaked") worn look of the coat.
I can see the whitewash getting layered on in the cold!
One suggestion/question/comment: Your exhaust- to me, too starkly reddish rusty. Tone it down, maybe- darken it? That, and there would have been whitewash slopped on it, too. I suppose that the whitewash would be blackened a bit?
Nice 38(t), Pard!
