Great job! I haven't seen The Desolation of Smaug for a while, so I actually couldn't remember what was cut and what was added at first. The movie worked great as a narrative and I really liked how the ending was re-edited. I felt that the whole dwarf-gold Smaug trick was too contrived in the original. I'm glad it was removed, and I also felt that the original cliffhanger ending wasn't a good way to end it. This edit tells the entire story arc of Smaug up to his death, and I think it works very well.
In summary, I recommend this edit. Great job, Masirimso17.
