Personally.. *SPOILERS*
Personally, I always thought it was kind of un-Zelda-like to have DBZ/Naruto-esque fight scenes, even moreso with this kind of music (don't get me wrong, I love all of those things, they just don't seem like Zelda to me).
However, the AWESOME character models (just like the manga!) kept me watching, and even though on base level the battle was kind of just clinkclinkclinkclink, you pulled some really impressive stuff with the tree getting chopped in half, Dark Link really surprised me when he exploded out of that smoke cloud and Link was unarmed and had to dodge, the way Link finished him off kicked a lot of ass, and I loved when Dark splatted into the tree and reassembled himself.
Sweet sweet stuff, very satisfying to watch.
My only question is, how come he didn't reassemble himself at the end? Is it because this time he was damaged by the Master Sword? If not, feel free to steal that explanation. :D lol
Overall I enjoyed this, and if you've been working on this series for the last 5 years, I'm incredibly excited to see more from you, how you've grown and evolved as an artist. Post more ASAP, I'll be watching! ^_^
