Hi John,
This is a lovely scene whether it’s peak color or not. I wanted to see if I could add some depth and modeling so downloaded a copy. Trouble is, you don’t have a color profile embedded in your image. That’s probably why the colors look muted and all of it looks fairly muddy compared to how your RAW file probably looks.
This is a good discussion about color space and how to get a jpg properly embedded with sRGB which is the only color space internet protocol language can interpret and display -
You don’t talk about what software you use for editing, but if it’s Adobe, this conversation will be exactly what you need. If you’re using something else, I’m sure the export dialogue has a place for you to assign a color space with whatever file type you choose.
