Something about me)

Hello everyone! My name is Marina, and I am from Russia.  I want to learn English so much!

The edits I made here were to make the sentence sound more natural. As a whole, the latter half of the introduction had a running sentence feel to it. So I made two separate sentences while still retaining the original message. *Note, you didn't make an error when you said, "I want to learn the English Language" but you can shorten it by simply saying English.

I study at the Far Eastern University of Humanities, my speciality is Public relations in social sphere. I want to find new friends, especially those who can help me with my english :)

The problem with the sentence originally was that "I am study" makes it sound like you yourself are the object "study" The reason I added in "those" between especially and who is because without that pronoun in there the sentence lacks an object and the latter half ends up sounding more like a question than an direct statement. Everyone would still understand the meaning of what you said, but this critic is supposed to aid in improving your English skills after all.
