This week's review practice! 

Hi Hiromi, 

Just some suggestions for you:

(1) As you are introducing the title of a specific movie, the first letter of each word should be capitalised. 

(2) You still have a positive feeling about the movie as you are typing this post, therefore, the verb should be in present tense. Next, the movie (singular noun) should be paired with a verb in the singular form (resonates).

(3) "heartwarming" is an adjective to describe something that causes you to feel a sense of emotional satisfaction. Hence, when you wrote "This movie makes me heartwarming", it gives the reader the misleading idea that you are the one causing someone else to feel a sense of emotional satisfaction. I changed the sentence slightly to "This movie is heartwarming...." 

"is" is a linking verb to link the noun "movie" with its characteristic "heartwarming". 

(4) You can also choose to write: This skill may broaden the possibilities for me. When we use "myself" as a reflexive pronoun, both subject and object of the sentence happen to be the same thing or person.

Example: I (subject is you) am baking (verb) a cake for myself (object is also you). 

In your original sentence: "This skill (subject is the skill) might broaden (verb) the possibilities (object is the possibilities) for myself." The subject and object are not referring to the same thing, so the reflexive pronoun is unnecessary. 

I changed "might" to "may" as the "might" is used more suitably for hypothetical (imaginary and unlikely) situations while "may" is used for something that actually is possible. 

Hope this helps.
Cheers

Practice of answering questions:) It continue in 10 weeks

This movie warms my heart and gives me a lot of gumption.
(Not sure what you mean by "gumption" in this sentence.)

Q2: What skill, language or hobby do you want to pick up this year?

My answer: This year, I want to pick up the skill of  web design skills. This skill might broaden the possibilities for myself my possibilities.
