I am aware this is an old thread so I’m coming in quite late. I hope you had a lot of success since; like myself I only know of a handful of photographers who use this peculiar film as their film of choice. I would say from my experience this is an ideal film for a gentle return to pictorialism. Retropan Portraits as well as still life or landscapes can embrace and reflect a lot of mood, with the right light you can achieve this dreaminess/ I think I just made up that word.
For me it is the film that allows me to express myself as well as act as medium for the way I see the world; because of my eyesight problem regarding colour processing I mainly turn to 4x5 bw , sometime ago I could best achieve the retro look on MF and 35mm which is visibly grainy, but I think was since discontinued.
Your examples are nice, as far as I can tell but quite straight cut, /from early days of your experience and for what you chose as subjects you could have used say Fomapan 400 with similarly satisfying results.
this is a soft film that if metered mainly at 320 and processed in retro foma developer can give you very satisfying results in terms of capturing mood and atmosphere. Prints best on baryta again by foma. All very affordable inviting for a lot of experimenting.
