I'll give you credit for your ambition. Even though you didn't finish, I hope you learned something.
I think your animation has improved some since then, but keep at it. The two things that stood out to me that needed some real improvement were the framing and cgi.
The framing was off in a few places so that we couldn't see everything. The cgi looked like a good places to start, but I have never done any of that so I couldn't really help you at all with that. I will say though that the scene where Sauron is forging the ring bugged me because you used the stacked base plates as the background and it looked pretty odd.
I hope I don't come off as mean, only trying to help. I did notice some nice details, like the broken shards of Isildur's sword. Just keep on improving so that one day you can complete an epic project like this one in the best way you can.
