Very creative idea, well executed. Although I was surprised she wasn't shooting civilians while she was tripping, thinking they were zombies.
But, the art style was nice, and fit the kind of humor you went with. The only thing I felt was lacking was I felt it wasn't physically dark enough; it seemed to bright to be a zombie apocalypse/crack den. You could also tell that there were looping scenes, where they're honestly didn't need to be, if that makes sense.
The echo effect on the audio at the beginning was a nice touch, but it didn't last long enough for you tell what it was (I didn't know what it was until I watched for the second time), and later on it sounded, like, hollow? I guess? Like talking into a pillow, while also underground in a mine, or a well.
Another thing I didn't realize until the second round through, was that the girl was Jill Valentine. Totally didn't notice; I think because she didn't have the vest or the hat. Still a cutie, though.
But, this short was awesome! I hope you do more parodies or the Resident Evil franchise in the future! <3
