Also important at least to me would be how much time you have to complete the production. 13 years ago seems like yesterday except that I had to edit by myself, on a 400mhz G4, what became a 40 minute short. There was 2 weeks of shooting and 1 month of editing time, 6-7 weeks total.
It was filmed on an early Sony Digital Handycam that recorded on digital tape.
To be honest, that and FCP (2 or 3) were enough for video (audio was another story but you don't have to worry about that in your case). A good photographer beats a good camera 99% of the time. Though if Part 1 was 5 days ago and you are rushing on Part 2, I imagine you have a shorter timeline.
Anyway, your equipment seems fine especially if you keep the same theme, though don't forget, to capture your audience you need to successfully convey your message to them/us. Part 1 (1st half great slow scenes, 2nd half too many different angles in a short time, as if it were mimicking CIS which is fine if your audience likes that) conveys the mood of the girl stood up, though with lack of color I it almost looked as though she had lip gloss without makeup. Also as a man I did get distracted by the repeated scene of her sitting down on the couch and forgot to be sad for a bit. Same with the butt shots. I get it, she's hot, but you've got to keep the mood of us feeling her loneliness. Maybe anatomy just easily distracts me.
If you work on what message you want for Part 2 and know what color mode you want to use (please anything but that Schindler's List style where only the rose is in color), see how your camera picks that up. If you find limitations, see how you can change lighting to compensate before you actually shoot. Since you know the setting, it should be easy enough. I really look forward to watching Part 2.
