Ahh, you must read NANA! ^_^ I'm so happy these icons made you want to pick it up...that's seriously the greatest compliment. :) NANA's been licensed already though they haven't released their first volume yet. You can, however, find scanslations in the meantime. There are links & info available at the yahoo group here or the NANA rocking horse forum here. ^^

And thank you for the comment on the manga coloring! ^_^ I haven't written tutorials in a while since I've been lacking enough time...but I'll be sure to keep this in mind! :D
