Wow, just wow....
That was great! I liked how "Still more Fighting" played when Cyan fought Kefka. To be honest, I think "Birth of a God" (also from FFVII--it plays during the second-last battle) is a great "vengeance song", and I was actually kinda hoping you would have that play when Cyan fought Kefka. Oh well...perhaps for the final battle in part 15, then? I would love it SOOOO much! Also, during the battle with Ultros, I thought you would use the song "Grand Finale" (it plays when you fight him in the Opera House), since it's like Ultros's theme song. Oh well...
Also, I noticed a slight...continuity error. At the end, we see the airship flying toward Kefka's Tower (that scene is obviously taken directly from FFVI, when Setzer's airship flies from the Opera House to the Southern Continent, and we see Vector in the background). But, that's not the Falcon. In at least one previous episode, you showed the Falcon--plus, it's the only airship that makes sense. But don't worry about it....
Otherwise, great, great job! I liked the graphics, the effects, the music, the style, and the emotion. Excellent job, and I know there are hundreds of people anxious to see the final part. Heh, it's been nearly a year since you came out with this one! If it's taken this long to make part 15, then it must be really, really long, and really, really KICKASS. I can't wait!
