Looks nice! I have on occasion looked for a rainbow toned example but have not found the right one yet (in terms of color and price combo).
I have one of those Bicentennial quarters somewhere around here but missing right now so I'll go with a hat pin!
I've got the 1976 Proof set, but don't have it photographed. No errors, just regular proof. But I do have a picture of a 1976 S Half that I found roll hunting.
