I find Iridient results from X-Trans to be harsh, over-sharpened even at the default. I don't think it looks natural.
I much prefer the rendering of Rawtherapee. I have found nothing that is as good.
I've just looked through your website, and like your cityscapes and "street" style. However, coming from old Nikons, which I take into Photoshop as Tiffs as soon as the Nikon programme permits it, I find everything shockingly harsh, which may simply be my personal reaction from looking at my own work, which has recently been shot almost wide open whenever that's possible; your great DOF could be where the surprise resides, but it still seems over-processed somehow. In other words, I think that I see exactly what you were describing using your least favourite Iridient, but to me, exists with what you use currently. This seems strongest with Death Valley, but having never been there, it may simply be accurate and I don't know that.
Digital comes with all sorts of problems never there with film, but without doubt, has many blessings too!
