Sure. I've watched it now.
I want to preface this by saying I'm going to be critical. Perhaps even harshly. I'm going to point out what I did and didn't like about your short as honestly as I can. A creator is protective of their own work; they've spent more time obsessing over it than anybody else and even if they recognize some of the flaws, it can feel hurtful when somebody points them out. That's not my goal-- to be hurtful-- I just want to give you my appraisal. I know this preface might not be necessary but it's as difficult for anybody to receive criticism as it is to create something so I feel it needs said.
That said, here is what I liked. I thought the camera work was good overall in terms of framing and lighting. I'm not a huge fan of the orange and teal aesthetic but I thought it worked naturally here-- it's mostly night and lights are mostly orange. The standout shot is where the man runs his head under the faucet. It was a nice, claustrophobic shot and I think the film could have benefited from more of that claustrophobic feeling. Overall, I think the film is shot and lit very well.
I also thought the actor did a fine job. I don't have much to add aside from that but I think he deserves credit for a good performance.
...
So let's get into what I thought was not so good. Unfortunately, it's going to encapsulate everything else. Sorry. But there might be a bit more good sprinkled in.
Firstly, pacing and editing. This film did not need to be as long as it is. Slow does not mean tense and this film is slow and not tense. I'm not going to go through it shot by shot but I started getting nervous the second I saw the front door being established twice in a row with looming camera pans. The shot through the gates or the second shot was all you needed-- not both. If you establish a door on a house, the next shot should be inside of that door. Otherwise, the audience is going to be confused when the next shot comes around and they're still outside the same door.
Too many shots linger on with seemingly no purpose. For example, there's the scene where he's in the bathroom and we
slowly follow the faucet down the shower head and down into the drain. Ok. What's the significance? I suppose you'll have to tell me because your short film does not. Is it supposed to be suspenseful? Well, it
could have been if something new was slowly revealed. Maybe a clump of hair or some blood. In fact, that's what I thought would happen... but it didn't and I thought instead "Oh, we're just running out the clock again." It's unfortunately consistent within your film right up until the end. Trim the fat!
You did have some good edits in there. The scene where it cuts from his hands to the choking was well done and I also thought the earrings were well done. I thought it was well executed how you showed their significance just by him peeking through a door and having them glimmer in the light while she put them on. More of that, please!
Now it's time to talk story. Specifically, thematic elements. Your film has a major focus on one thing, intentional or not-- water. He drinks a lot of water, he has two scenes in a bathroom, we see a lot of faucets and a lot of water themed... stuff; it's a lot of water. What role does water play in the story? None. It's just there. Why are we seeing all this water when it has nothing to do with his own guilt or anything at all? Wouldn't it have been better if he drowned her in the bathtub or killed her in the shower instead? If you're going to have a reoccurring theme in your film, make it matter.
The story also has a major flaw in that there's no horror or suspense whatsoever. We know almost immediately that he's killed somebody and is haunted by guilt or a spirit of vengeance. Alright, that's fine, but what is the conflict and why should I care? All this guy has done is drink water and mope around a house. We know absolutely nothing about him so who gives a shit if he has bad dreams or feels guilty? What should I feel a sense of horror about? There's nothing to work with because we don't have anything to weigh it against. We know nothing about these people aside from them existing. It's a story with no substance-- it's like trying to grab a handful of fog. The lack of characterization kills the entire film.
The score... don't use Psycho string stabs. It's just silly. I understand you're working low or no budget but no score would have been better there.
...
And that's about it for now. I apologize if I've come across as callous at any point.
