Okay, I watched the opening and the ending, mostly because I was curious how it stacked up to the ThereAndBackAgain 3hr edit I watched recently. And I'll have more thoughts once I finish, but I did have one big suggestion.
Love the smooth edits. Love the cue you took from ahobbitsholiday by sequencing the prologue with the song in Bag End. Loved, also, that you DID keep the conversation about the Ring at the end, unlike the 3hr edit.
So this is a big suggestion, and I don't want to be creative for you, but I think we NEED to see Thorin take the deathblow, for closure. We also need to see Fili & Kili die, and even see Bolg die. So I suggest the following:
Using the Dwarf theme--I would love the entire song from Bag End, including the extended theme--add to the montage while Bilbo is knocked out. To the Eagles and Beorn add jump cuts of Fili & Kili dying, Tauriel fighting, Legolas killing Bolg and finally, a few jump cuts through Thorin's battle with Azog, in which Azog is, for all intents and purposes, just the big strong Orc who takes Thorin out.
