Well..
Okay, first of all - too many zelda movies in newgrounds as it is, only a handful have actually been good. All the bad ones are the ones that are trying to be serious, mainly because:
A: story sucks
B: graphics suck
C: voices suck
While you did have a good story, and I admit I would've liked to see something like that happen.. the voices were horrible, they should've just been left out, I don't mind reading text as long as I don't have to click on anything while viewing the movie. The animation was pretty stiff, it would've been better if you animated a few more scenes, or did the traditional "action" scenes from old school animes in order to do it more productively and better. I watched the whole thing, but at the same time I felt pretty embarrased because I watching it. That's not something you should shoot for, when people get embarrased of watching a flash/movie. The music just killed it too... the first song was okay when the city was being attacked, but then it just went on playing more alternative music that would be heard in a LoZ game/movie. The music just seemed like an excuse to make this flash in the beggining. If you look at the top 50 flashes, you'll notice no one really uses any music like that.. and if they do, they did it right or semi-right. Anyways, hope you improve on this, but i'll give you this - it was lengthy, good story, and good drawings - (just bad animation).
