Thanks man. This was really helpful. btw i m planing to upload a behind the scene but was a little bit unsure, but now i m gonna do it for sure.

Thanks but you cant really plan marketing on a no-budget beforehand , Since you have to spend whatever you have to increase the quality of the short. and after that there's no more money left for advertisement :'(
But thanks for the input anyways. I'll try to plan out my marketing strategy beforehand on my next short.

As someone already pointed out in the comments , the lighting was inconsistent which made a little confusion.BTW the pic quality was pleasing to the eyes.
I feel the flashback scene at 01:32 greatly disturbed the rhythm of the story.Maybe you could have shown that scene at the very begging.
Other than that it was amazing overall.

Thanks for the tips, everyone.
