Been playing with Darktable in this odyssey of learning and I like this B/W sorta look, selective color I believe it is called. A little research tells me this style has fallen out of favor in general. Looking for thoughts and insights please.
Edit:
Who cares what is in or out of favor. I feel the effect works very well on this image and I like it.
Its nice…I am not one to provide educated feedback but just doing a personal visual assessment maybe you could blur the background a little more so there is no conflict with the moss/fern and your mask missed a bit of the ends… some combination of feather, opacity of the mask (not the module) and the contrast of the mask might catch that … also the details slider if might help to catch some of the fringe elements…
I’m with Terry…make the art that you like …
Apparently you can pass off thin air as art in the art world so I think you have a pretty wide open license to do whatever you like… 
Cool! Though, I think the subject is moss, not fern.
Duh! lol, don’t know where my head was. Thanx.
Thanx. I will adjust and put up an edit later today. Amazing what the art world pushes.
This is often my experience when I try to add extra blur to a background.
