Not bad, but could be improved
Well, I think I'm not gonna say anything you have not read before. ^^U
You should have elaborated this a bit more. Background, music (a loop would be fine, because it stops after some time), text (as some people have said to you: it is occasionally hard to read), animations (or at least some changes in the image, depending on the thing you are saying)...
In short, a bit of customization and not just a static image and plain text. Also, there are some typos over there and a little lack of information (for example, neko characters are just humanoids with some feline characteristics as neko = cat, not any animal - that is kemonomimi, wich also includes neko characters, of course).
I see this more like a blog entry than an informative flash... Very, very simple. But, hey! I think this could be a great idea to support and advise all those people who don't know about manga or anime!
Just keep it up and improve your flash and drawing skills! I hope to see more of your work in the future! :D
Good luck!
