It's just a preview
I don't get why you said that you'll make the paintball masks later, I mean you only showed their face once for the name intro and the rest of it is just the back of their heads. So considering that they will be playing wearing masks and that you didn't even really use their faces all that much, it seems not well planned out. Nevertheless, the movie has enough potential to be good one day and that one day when it's finished, I'll give a better vote then 1 it's gets today
