Wow! It’s a neat improvement from my first post!
As for the softness, I agree that it may be a post processing issue. I used GIMP, and I usually keep an eye open for exporting quality. It may be this but I doubt it. What I suspect is that I had maybe used a blur to remove the apparent noise. I had probably sharpened the picture after, but the results shows…
I’m not sure of my theory, since I edited it a little time ago and I don’t have a big memory, but that’s the only thing I can think of.
