This is very nice overall! I love the section just after Ryuko comes out of the fiber cocoon! ^^ The animation is quite fluid in places, but then a bit jerky and sudden in others. The expanding of the fiber cocoon and the final pose are the sore spots for me. Maybe try making the cocoon expand more smoothly, and add some of the subtle body twist that Ryuko does at the end of the transformation. I also feel that the close up shot at the beginning could be cleaned up and refined as well.
Woah, yesterday I started a project for making the same scene in pixel art too! I was to slow... anyway, great job man! >:)
Wonderful stuff man. The transformation was a little boring, but it's still good.
you are awesome.. I love this anime
