The review is in...

One of the local community theater groups has its own annual awards.  Each company submits one show from its season for consideration; the Yeomen of the Guard I did earlier this year was the one that company submitted.  A few days ago we received the consolidated write-up (I think different adjudicators rate different aspects of the performance).

I'm excerpting the comments on my role not because I like them, but because I agree with them; starting to beef up my lower register once I was cast wasn't nearly enough time, and I need to learn how to do "commanding stage presence".  With that, here's what the judges said:

Acting
Dame Carruthers’ role requires a certain robust authority which [I] lacked and she did not make a very formidable Dame, despite her confident stage presence.  [Well, I like that bit about the "confident stage presence". ;)]    In Act II she picked up energy, and the duet with Sergeant Meryll was a nice romp. [Because I got to dance! :D]

Singing
[Carruthers] and [Sgt. Meryll] were both weak in their lower registers, especially for Carruthers in her Act I song, lacking the required range. 

Throughout the rehearsal process I felt like the weak link in the principals chain.  While I'm sorry to be right about that, I also feel that, if I were to sing the role today, not 6 months later, that weak lower register would have more power & resonance.  Ah well; I'll keep plugging away and eventually I'll be ready for the roles I've already done. ;)
