I'll take you at your word, but to me it sounds instead that you're kind of bored with German, which is why you're looking at other languages. I'm not criticizing, though, it just kind of feels like things don't match up.

And I wouldn't be so quick to lump Venezuelan and Mexican Spanish together. Well, they're going to have serious differences in pronunciation - that's for sure. But they may also differ in pronouns. Although I haven't looked at Venezuela, I know for example that in the Argentinian dialect there's a pronoun that doesn't exist either in Spain or Mexico... And then you're going to encounter idioms, misuse of which, as I understand, leads to comical misunderstandings more often than not, because Spanish-speaking countries are strangely fond of applying formerly innocent words to obscene activities, regionally, while in other countries those words remain "clean".
