Hello there. The 'should' means that there's some sort of standard on how girls from Phoenix look, and that the speaker looks different, and therefore stands out. Hope I helped.

They basically mean the same thing because if you've never been to Korea, then you haven't been there. On another note, if you change the question and specify the time and say something like "Have you been to Korea this year?", then it will make a difference.

My Favorite Colors

Today I will talk about my favorite colors.There are many kinds of types a lot.
There is red, orange, yellow, green
blue, purple, pink, white and black.
My favorite colors are white, black ,pink, sky blue and yellow. I think I like clear colors.
Sky blue is a very clear and beautiful color.

"This is your fault." would be the more correct sentence if you wanted to put the blame on someone. The above sentence though, simply suggests that you are the mastermind of the action done. It can also refer to something good, or even genius.

Good job = 잘 했어요

About the last movies I saw

In the last two weeks, I saw the following movies: The Hateful Eight, Black Mass, Zootopia, The Fifth Wave, Deadpool and The Martian, some in home and some others in the cinema. Most of them I really liked, but one I think it was a huge waste of money for me (because I saw it on cinema). (Do) Can you guess which one it was?

By other side , do you have (your) a favorite among those movies? Why do you like it?

Explanations: I didn't know what you wanted to say by "By other side" so I didn't know how to correct it.

I added some words in the last sentence to make it agree with the sentence before that. You asked us if we had a favorite among the movies you've seen and that's answerable by yes or no If you didn't expand the last sentence, it'd be like asking "Why do you havea favorite?" which I'm pretty sure wasn't your intention.
