All that build up! Now I want more, dammit!
Argh, this animation is really, really frustrating as a teaser. All that build up and no real story progress. Ah, well, expositions tend to be like that. Please continue it soon!
However, that opening battle was spectacular. The frame rate was a little low, but the art was still excellent- that flip near the end looked stunning. And the music! The song is beautifully syncronized with her transformation; and I cannot over emphasize how well you pulled off the transformation shot. If you continue doing this as a series, I expect the fight scenes will be "Matrix" dramatic.
I've looked at most of your stuff here, and you put a lot of emphasis on the 'damsel-in-distress and her protector' theme, and you do it very well. I want to congradulate you on being able to work an old theme that most have abandoned without making it seem trite or hackneyed; these days seeing anime-style girls with watery eyes and quivering lips often means you're looking at some kind of hentai.
Keep up the good work, man!
