Just a few corrections in addition to Adriano's correction:

My favourite are Mass effect, dragon age and I think that both disonored and deus ex are amazing,  although I don't usually like "stealth" games.

My biggest favorite hobby is drawing, as (does this as means because?) I love animation and character design. I also enjoy a bit of reading and web-design. (in Englisch you do not use comma before and)

Now I'm student (you can use currently or at the moment at the beggining of this sentence or after "student"), but it is my last final year. I'm writing my graduation work Master (or Bachelor) thesis. (thesis=дипломная). 

Although I'm a little bit hesitate unsure about my english, but without practice I can't fix it. (you should use comma when you have Although)

I would be really glad if you could help me.
I understand all what people say, I can read a books (eather a book or books) in english, watch movies (a movie is grammatically ok but you making a list so it is better to use plurral)   but i've got a little, or maybe a big problem with expressing myself in english. I find it hard to describe things in proper ways. Maybe I am a little bit nervous or just unconfident. So, can i count on you? -__- I'm really tired of it. I know it may (or might) be it's sound wierd.

I wouldn't say you have problems with expressing yourself :). Just be more confident ;) 

My first time

Hello! I'm new in on this website. I have been visiting vitited many pages and now I thing that now I'm ready to write something but I don't know about that what exactly. Ok, I think I found a topic to speak about (or to write about).
Last weekend I went with some my friends to one the disco and we have had a problem. When we are were talking or dancing, I don't remember exactly, my friend noted that your his (- if it was his jacket or mine if it was your jacket) jacket had was missing. First we thought the jacket had fallen and started looking but we din't find haven't found it and were it was impossible not to found it because it's rose and it's a color that you can see easily! And I thought it was possible that other person had stollen. And Them we begun to look for around the disco and near we see saw two women (woman is single, women is plural) with a similar jacket. My friend took it off and then we began to discuss about how strange the jacket had was missing. One of the woman said she had taken down but it was impossible. (Do you mean next: The woman said that jacket was on the floor and she lifted it?) Then two womaen pretended to be angry and they went left. 

I'm sure they tried to steal her jacket because in near disco someone has stolen my Iphone iPhone (just marketing correction :)) three months ago.

And thats is (that is or that's) all. Bye and thank to reading.

Nice writing but I would recommend you to go to another disco next time :)
