Sharp shoes, Stitchy.
RD, don't let Butch corrupt you with his odd ways! And I think your shoes look fine, too: true, I'd also have maybe gone with suede or a scotchgrain derby. A boot of some sort would be even better. Or sure, a loafer if you're lounging by the fire. But as not so long ago tan shoes were only casual, I don't find yours especially jarring in this context.
My line of thought was that out of all oxfords, full brogues are the most casual. I thought they were versatile enough to cover the whole range from casual suits to streetwear, but maybe I was wrong!
