English: 

Hello, my name is  Евгений and I'm 17 years old. I like anime, manga and J-ROCK.

I'd like to study Japanese. 

Point1>> 

Japanese often omits the definitely subjects. Especially, like  「私は」. Because your memo has been written by you and this topic is about you not others. 

Point2>>  

「です」is more polite. You'd better to add 「です」 if you use one in the first sentence. Thus, it brings unity among the letter/message.
