Looking for help with my presentation

[liz-weir.livejournal.com]

Hey! I was looking for a community where I could look for ansers when I have questions concerning the Russian language. And I found this one. My problem is that I have to give a short presentation about the author Dostoyevsky. I am now done with my text but I am absolutely sure that I made a lot of mistakes. It doesn´t matter how often I read it, I always have the feeling that I did something wrong. I just don´t know what. Maybe someone could check the text and tell me what kind of mistakes I made? That would be very kind, I really want to get better at the language.

If his is not allowed please tell me, so I don´t post anything like this again or delete the post. Thanks a lot.
