A few corrections: it is either 'der Zahn' (singular) or 'die Zähne' (plural). You have used the English plural form, as you did with some other body parts. However, since der German forms are otherwise all singular, it should be the same for all words in English - so no additional 's's, please.
Also, you have used the same word for 'Bauch' and 'Magen', which is confusing. For Bauch, however, a much better word would be 'belly'. And for 'Po' you'll admit there are plenty of alternative words used in English, and not just slang ones. So a few more type-ins here would be sensible.
