@rhol -- Yikes! Who did you mix him with? Nice character blend, whoever it is, even if he does look a bit young. As for speaking with the spirits and investigating paranormal mysteries, Archive of Our Own (a.k.a. AO3) has all kinds of Sherlockian fanfic with those themes. Only fitting, given Sir Arthur's interest in the occult. 

Adobe Express has free beta access to Firefly, so I tried it out a little this afternoon. Some things not bad, it gave me a couple chairs to try sitting Watson on. Unfortunately it mucked up the coloring I'd used on the walls by totally ignoring my curves and hue/sat layers. Worse, it would not let me download my edits as a .psd file, only a .png. With no layers and everything merged. But, it is helpful as a guide to where to place that blasted chair and I'm certain I can find a workaround for the things I don't like about it. Oh well, that's why they call it a beta. Anyway, here's what I got. Do feel free to mark it up, point & laugh, etc. Just no rotten tomatoes, the stains are a right b**ch to get out. ;-)

Colour sucks and will be fixed. No, I don't mean the sweater, rather attached to that pattern and it suits the story. Would be ever so much easier if I could just transfer it to any of the other renders from the same prompt that need less work but have unfortunately plain or even ugly purple jumpers. So far I have not figured out how to make that design again. A couple of times came a little close but no joy. In Daz or Poser I could pull that trick off with shaders, too bad there is no material room equivalent for Stable Diffusion. 

See? This one needs minimum fixing and I like the room and pose and the chair and ... well, everything except that dirty pink it made the jumper. In spite of my specifying the same three colours as before in the very same order. Might still do something with it, though. Too good to waste.
