I guess I'm the odd one out here. I honestly, and overwhelmingly, prefer the original photo. It has a sense of serenity and grandeur that the edits - skillfully done as they are - only serve to diminish. The negative space of the original imparts a real feeling of vastness, and shouldn't be cropped out. The muted colors of your original make the glow of the burner stand out all the more, like those photos of a single lit window seen in the distance of a nighttime snow scene, or a Thomas Kinkade picture. Saturating the surrounding colors reduces the dramatic luminosity of that lone burner. All in my opinion, of course.
I wouldn't touch it.
