What I liked about this short were things such as the choice and use of the upbeat music, and it being broken by the sound of the running water, which was jarring but in a good way. The music throughout the short worked well.
The shot of the wine glass being filled and having it stop so it's level with the top of frame was a great touch, as is the use of static camera angles, and overall the framing of shots was great.
I liked that the negative representation of her mind wasn't dressed or done up to look the way cliche evil characters generally do. The actress did a really good job of playing the opposing representations of the character's mental state.
The only thing I'd say lets this short down is re-using the upbeat music again at the end. I think it would have been better to end on the scream and then just cut to black.
Overall a job well done!
