Some Words about Myself

Since you are the writer, using the reflexive myself makes most sense. However, me is not entirely wrong: "(Here are) some words about me."

I am learning English, because I'm interested in different cultures, and their mentalities. It also helps when making friends, travelling, watching English-language./american movies...etc and so on.

The word coz is slangy, and it looks terrible in writing. Be wary of this.

The next two languages I would like to learn are Italian and Spanish (then probably it'll be Greek). :)

Remember when to use capital letters! Also, it's a good habit to write numbers as words.

My native languages: are Russian, and Ukrainian.

Try to write a proper sentence instead of relying on punctuation and point form. This will also improve your spoken English.

I enjoy rollerblading, skating, esoteric literature and heavy music...

Good work! I'm not sure what you meant by "hard" music.

Great job! In English, we use capital letters for proper nouns such as names of countries :)
