Content looks great so far, pretty good work with the bamboo.

I'm studying Japanese for my herbal investigations, their herbal medicine is advanced and somewhat different from the Chinese. For learning Chinese/Japanese characters, James Heisig's "Remembering" books are my bibles but I've branched off from them to Alfonso's Japanese Patterns' series which were popular in the mid 1990's. I've looked everywhere for the full audio, which was once available on cassettes but no luck so far. Another good book for learning Kanji reading is the old ""The Kanji Way to Japanese Language Power" by Crowley which, through written in the1950's, is still good (no audio).
