Good idea generally, the colour idea was something else. I liked it, but I think that if you're making a tutorial, you definitely should make the most advanced you can, and the one that looks best. I liked the first blood and was a little dissappointed to not have the tut. for it.
I suppose it's helpful for those who would like to animate blood in such a manner, but even a flash noob like myself can animate blood better than the way you did in this tutorial. Not to mention, the grammar needs some serious improvment. It's not a bad tutorial, but only a real flash noob would find that they actually learned something from this.
Sorry, but you need to improve your own skills before you go on making a tutorial. 5/10.
