You are one lucky guy! A fantastic bike and, from the looks of it, great weather to ride it in!
I also like the wheels very much. Go real well together with classic, thin steel frames. Though I wonder if they look good with black tyres too. Please take a photo should you ever mount such tyres.
As long as saddle and tape are colour-coordinated, I think black or white bar tape would look equally well. Especially since the bike has both colours as well (fork and chainstays).
The only thing I personally would alter is the bottle holders. In my eyes those elite steel holders don't look good on any frame, not even steel ones
I would prefer modern, carbon ones.
