It sounds like you've had an amazing week. Did you ever get a chance to meet Grigor and speak to him? I was looking for you in the player's box but I didn't see anyone in a purple floral dress I'm afraid. I did see Mikael's two little girls and they were cute with their Grisha headbands.
The result was disappointing, especially as Grigor's game broke down when serving for the 1st set and in the tie-break but that shows he still has work to do on his mental strength and it is understandable as this was his first final. For the most part though, his game matched up well against Murray's and if he had served as well as he had done earlier in the week, it could have been a different story.
His ground game was excellent and that should give him confidence going into the AO. His backhand has really improved and as recently as Basel and Paris last years, opponents were winning points by attacking it but they won't be able to do that anymore. Grigor's backhand slice drove Murray crazy and his backhand down the line was incredible throughout the match.
I'm a little surprised he is still playing Sydney but I'm sure they know best. Here's hoping he has another good week
