Almost perfect except for du (at the beginning of a sentence or when used as a direct address in a letter) and Fuchs (as a noun) would be capitalized. However, there are many not exactly necessary grammatical difficulties in the German language. I have talked (respectively written) to quite a couple of people who were convinced of the near nativeness of their German while in some cases it was really not easy to figure out what the person meant (the same is true for the written utterances of some native German speakers though

).
Don't get me wrong, German can be quite a beautiful language and in some cases it is clearer than English (e.g. in most (not all) cases you know about the gender of a person the moment he or she is mentioned while in English it takes further explanation if somebody mentions for example a friend, colleague whatever), but it also is more complex and I suppose there are more sounds in German difficult to pronounce for the native English speaker than the other way round.
Aber ich mˆchte Dich echt nicht entmutigen. Wenn Dir die deutsche Sprache gef‰llt und Du mal Fragen dazu hast oder ich Dir sonst irgendwie weiterhelfen kann, dann lass es mich einfach wissen.
