Wow! This is absolutely amazing! Congratulations! 
Little did you know, your hobby project would come to inspire and awe fans!
I’ll share this tidbit of my personal childhood since we’re both fans of the franchise. I was about 2 or 3 years old when my mother took me to the cinema to see Ghostbusters. I was not afraid of any of the ghosts, but I was absolutely terrified of the Stay Puft Marshmallow Man! LOL! 
BTW, the choice to add the inspired Ghostbusters theme song to your video was excellent, indeed!
