Try harder!
Your animation sucks. It's not an original idea and it doesn't really add anything new to the meme, the lips and body motions do not sync with the loop, and the graphics are anything but cute, which begs the viewer what the heck he or she has just watched.
Things that particularly stand out? Miku's head color is different from the rest of her body. Her hair's too light and doesn't make a hair-like motion. Motion's pretty awkward, and that's to be expected since the meme was originally 2D. And the flash lacks a preloader. The loop is fine, but if possible, preloaders are a must.
