Thank you so much! I've really been intrigued by these two, even from the start, and it does make me wonder if Ollivander could have been used earlier by Voldemort, given the way he is in awe of Voldemort (as seen be Harry both when he first meets Harry and then much later in the books).
I'm glad the scene with the dragon worked for readers; dragons play such a minor role in the series and there's not a lot of information re: heartstrings, so I imagined how Ollivander could go about it humanely.
I was really quite taken especially with Ollivanders view that there was an entire scene that didn't make it into this story, so I hope to write more of him soon.
