You've put an incredible amount of work into the film and well done for that...it's the only way to make films!
Nice that it's a complete story too...so many shorts seem to be like a clip from something bigger, one observation though...and it's an observation not a criticism...
I wonder how much better the atmosphere of your film would have been if it had been shot on film ( 16mm or even 8mm )...for a semi horror flick the footage from the dslr
seems very clean and sharp...or it may be that it was shot in bright daylight. I always expect things lurking in the shadows in suspense and horror. As I said my own observations, not a criticism.
Keep up the hard work...
