:D keep at it!
Good points (right off the bat) volume was even. Sometimes, in flashes, people have music and sound effects and don't balance it, but you actually did! it wasn't ungodly loud compared to the music, not was it too quiet to hear, it fit, well done!
improving: consistency, you had the blood on the arm switch or disappear at times (disappear when she sighed, switched toward the end)
a few more frames as well would makes things a little bit smoother, although it would take a bit longer. if you want to have fewer frames like that, maybe have sound effects and do short bursts of animation... *shrug* whatever your style is ^^ at times fewer fit, at times it was a bit off, overall pretty good.
i don't mean to get down on you, i really liked it! :D i hope to see more from you soon ^^
