Rudeofus, is your output analogue (ilfochrome)? Or are you planning to project these? Otherwise I'd shoot normally on astia and slightly adjust warmth afterwards.

Oh and provia 100F blues up on me all the time, if the colour temp is the slightest bit off of 5000K. Astia does much better for me in mixed light and when skin tones are involved. Provia 400x does better than 100F for skin tones, but still not as well as astia. Just my experience.

P.S. there is no issue in your shots that I cannot correct in about 5 sec. We can't discuss the means here but... no big deal at all.
