You know what, I'll just go ahead and download it right now! My brother bought me a How-to-Draw Manga book, even though I already know how to, and I was using some of it's tips in it. I also tried some shading techniques, but they're a work in progress (have you ever been to COSI? the one in my city has an exibit called "Progress", and I LOVE it! It's my favorite exibit).
