After the death of his father, a young boy finds comfort in stories of the "wild west" while living in New York City, 1938.

Agreed with Phil - what is the goal, the stakes and the antagonist?

This hints at an interesting story but the logline is incomplete. What is the challenge that the boy faces? i.e. what does he want? what's stopping him from getting it? and what will happen if he doesn't get it?
