My new, first and only story.

Hey guys.. I need a favor. I wrote a story but I'm quite unsure about it.. I'm a new author, English isn't my native language so I'd like you to read and comment it.. I want to know if it's good enough.
I wrote about 4 chapters, can you tell me if it's smart idea to continue or I should just drop it?

Thank you, I appreciate the time you'll take for it.
