Notes:

Really nice job on your entry, Cem. A few rules to keep an eye out for:

1) In English, all language names (Russian, English, Japanese) should be capitalized.

2)"i" should always be capitalized to appear as "I." 

Let me know if you have any questions about my other corrections! I look forward to helping you with your studies.

Best,

Charlie
