Anime tutorials

I was curious and hoping that someone could point me in the direction of tutorials that work well on anime/cartoon images? I can make icons with people and real life pictures, but my weak point is anime or cartoon icons - tutorials I use definitely don't have the same effect obviously and I haven't been able to find any tutorials [or ones that I like] for anime images.

If someone could point me in the direction of some, I'd be very grateful - I'm still currently looking myself, so I do apologize if there are some obvious ones out there :( [Like, I know one was just posted a few entries down, but none of my images are that dark].
