I did really enjoy this trilogy. My impression during the first book was that it was eloquent but got off to a slow start, but ending on an exciting note. The second book tried to bring too many threads together and ended up having lots of viewpoints from seemingly disconnected people. The third book(s) brought people together so there were fewer "groups" to follow, and wrapped everything up pretty nicely, for the most part. The ending can be described as nothing short of epic, with a very vivid scene and wound up nicely with the hope of rebuilding. It was a clean trilogy and very, very enjoyable. If I was a huge Tolkien fan, I'm quite certain that this would be pure gold for me. I really liked the book and would recommend it.
That said, there were a few things that in my opinion lacked some polish (they might seem numerous but they are really more of nitpicks):
A few things off the top of my head that I didn't think were really answered: what the drink continually served to Elias was doing to him (unbinding his soul? I don't know). Why was Prester John's body completely preserved? What was it about Camaris that Towser did not tell? His sin?
A few complaints?
There was a foreshadowing of Simon's ancestry (Miriamele thought his face looked like someone she'd seen before) but it wasn't something anyone reading could have guessed. Sort of out of the blue there.
Bright-Nail turned to dust (said in passing in the midst of everything else). Nothing said of the other swords or even why that happened. Not much focus on it and no one even talks about the swords later.
The timeline for Simon's ancestor (Eahlstan) didn't make sense to me. He apparently ruled hundreds of years before, but died killing the dragon, at which time John took up the throne. One would have expected the king to have been at most Simon's great-grandfather, but how could that be if it was many hundreds of years earlier? And in either case, Why would Simon have such a strong resemblance to his ancestor of 500 years ago, so much so that the statue in the throne room reminded people of Simon? I also didn't feel like there was ample reason given why Simon wasn't told this by before by all the people who knew about it.
There didn't really seem to be a strong redemption or forgiveness for Miriamele. She had confessed her sin to Simon, they both seemed a little hard toward each other, and then suddenly she asks him to not leave her, he says he loves her, and they have sex. I would have liked to have seen her "purified" or "redeemed" somehow.
The last paragraphs wrap up with Eolair being told about Maegwin's sacrifice, which I suppose is nice that he knows but it was an odd note to end on and I didn't really feel like it gave Eolair closure, relief, or joy.
So maybe I should just make up my own ending and wrap up all these things :)
