hmmmm...
Well, i realize that while you did obviously put a lot of time and effort into it, this flash is really only subpar. While the story was semi-interesting, it was all just focused in on the one battle. Which is fine, if you had a good animation to make up for it. But the voice acting was terrible, at points the subtitles (which I found unnecessary) weren't synchronized correctly or said the wrong thing. Also, while the still frames were good, you focused too much on zoomed in objects or faces all of the time. Once or twice for dramatic effect is okay, but when you do it all the time it takes away from the action. Which brings me to the next part of my critique - there really wasn't any. This is supposed to be an epic final battle, right?? So why aren't we seeing any of the action? I think the part in the beginning when Link and Ganondorf crossed swords was the most action-oriented part of the whole flash, which is somewhat depressing since the way they were standing upright like that made it look awkward. They should have both been leaning forward into the strike.
But anyway, in summary:
-The art was detailed, but not necessarily the best.
-The action was severely underplayed.
-You focused too much on the wrong parts.
Go back and fix some of this stuff, or perhaps just scrap this entire project and start from the beginning, and you might be able to come up with a better flash.
