I congratulate you on your turnout and would imagine that you were in the top 1 or 2 percent of being dressed up for the event. You are however not in highland semi formal attire. As per my previous post, there is no highland semi formal attire.
Your jacket is formal day attire, the equivalent of morning dress,( think Ascot or being invested by HM Queen Elizabeth II) your sporran is formal evening attire.
Change your tie to a black bow tie and you are at the lower end of black tie formal.

Personally, I'd like to see your kilt to come up a inch or more. Show some knee my good man.
