IR portraits look great if you're into that kind of look.
I did some of my wife a couple of years ago (
TP link) just to see how they would turn out.
Is yours a long wavelength conversion? Mine was 590nm so I could do false colour and just whack a 750nm filter on for B&W.
Either way, I think your processing would suit a more sinister movie (there's a scene in the horror movie Rec that is shot with IR that has that similar look to the eyes), but that's not a criticism, as I think your take on the theme is very good.
Doing a video is really cool too.
