Hi, I like the images. They work very well together as a series and evoke some memories of my own goodbyes.
As for C41, I have only done it a few times, but at a lower temperature (25C). As far as I know, this gives you a little more wiggle room in temperature and timing. I have never tried developing at 38C. Normally I am using the digibase kit which separates the bleach and fix steps.
