Well, you've really got a scheme for performance art right now. I probably wouldn't have brought it up if you work didn't have an appropriate structure already. Simply concentrating on the action within a series of photos can be a kind of performance art.
I did some performance pieces in graduate school and they were always presented as videos. I did the performance action privately, but the video document was my presentation of the work.
You are already creating a unique and complex situation in the making of these images. It is more a matter of emphasis. You seem to be creating an action in order to generate images. All that I am saying is that you might make the action a priority and use the images to present/document the performance. This might already be an intention of yours. Perhaps you move between these motives without much concern. But you might enjoy being more deliberate about these distinctions.
I do want to say again that this is wonderful work that you're doing. It is very rich and evolving in a sensible and exciting way. I don't usually have so much to say about another artist's work. Please consider this an appreciation!

Dabei geht man als Patient immer davon aus, dass die "Profis" alles im Griff haben. Man verliert als "Hilfeempfänger" ziemlich schnell den Blick dafür, dass der Gegenüber für gewöhnlich auch so etwas wie ein Leben hat.
