Creatively, I'm shooting portraits... Negative offers the best skin tones and exposure latitude. The scan with the camera was a simple scan for review purposes, not ultimate quality.Not sure what exactly you're going for creatively but starting with slide film might yield "better" results in this workflow. Slide is a lot thinner than negs and can be scanned with less light/noise than neg film. It also has a lot less exposure latitude but I think that's a good thing.
I went the other direction -> I've been printing my digi to film recently via Impossible Instant Lab to Polaroid and an iphone. https://www.the-impossible-project.com/instantlab/
Gotta love the ultimate project and what they've done.
