Autodidactically means self-taught.

The only typo I saw is that you wrote "jozu" when it should be "jouzu" (that, and you're not using any kanji, but that's not an error per se). The grammar seems a bit off on the sentences using "hodo," although I'm not especially familiar with its usage myself.

Your use of "hou ga," while alright, seems a bit stiff and unusual to me. For instance, if you're trying to say "Kagami is prettier than Tsukasa" then I would just say "Tsukasa yori, Kagami wa kirei desu."
I could be totally wrong though (but I don't think so).
