I love this photo, steeped in atmosphere, truly stunning!
Yes, I think you're very brave attempting any colour processing in a home/studio set up. During my many years spending hours at a time in the darkroom, and being before the internret was even a thing, everything was geared up for making prints, and with the more complicated processing and the expense, I never did venture into colour developing and printing, leaving my colour work to a pro lab. Which was really no where near as satisfying as when producing your own prints. Hence I stayed mostly B&W for many, many years, and only as the digital medium and editing software started to really get to the high standard it has in recent years, have I really got properly into colour work.
It's about being in control of the whole process from click of the shutter to the viewed photograph. After all, an artist is hardly going to let somebody else choose his colour pallet, which is, to some extent, pretty much how I've felt when collecting colour prints up from the pro-lab, a really good pro lab too. The qulity was hard to fault, but was now influenced (read as tarnished,lol) by the thoughts of someone else as they judge and make compensations and adjustments for colours and punch etc.
I take my hat off for attempting the film processing! Have you attempted analogue colour printing too?
