I was just going to use the files you posted here so no worries
With the sources I've meant the3D data, which is done in Blender 3D.
Just in case this wasn't clear.
Maybe, with some luck, i have them stored on a DVD RW somewhere, and can't find it right now.
The whole motions of the up and down dancing on the cross was quite some work, so some more work to improve the result may be worth some more work.
So maybe I find the original files and work on it again.
Then probably i wouldn't 'nail' her (with nails) but instead ram some slim sustaining iron rods through the whole structure, fixing her in position at her feet and hands.
Then the eyes should vary more along the clip, they are most of the time in this shocked staring-mode, it should be more kind of exhausted suffering more often.
It's about 6 minutes in length of suffering, stemming up, sinking down in agony again and again, 6 mins of always new painful movements without simple repetitions , looking at her exposed body from different camera positions, and perfectly looping in the end to the starting-position (after 6 mins of dancing on the cross repetition won't mind)
