All three look fine to me, but if it's possible, I'd like to see some red in your neck tie, just to bring out the red stripes in the kilt. As far as the Russian pocketwatch goes, I'd say if it looks good, wear it. It would be even better if you can get it running again.
All in all, this is a well-put-together kit. Don't be surprised if you wind up answering all sorts of questions all day, from "the question" to Sir Walter Scott to Scottish miltary history and everything in between. Good luck!
