Charred Iridescence

Thanks for everyone's comments on my previous waterfall image. Really appreciate it.

Here's another image from the same trip. It seems we were always sticking our noses inside burned out, weathered old junipers and lodgepole pines during our trip to the Sonora Pass. I was particularly attracted to the reflected light inside this lightning struck, burned out old tree. The charred remains were reflecting the outside light nicely including the blues from the sky. But also the iridescence struck me, like the abalone shell. I tried to process this so the colors showed enough, but didn't want to ruin the effect by oversaturation. I would be curious to your thoughts on the processing here. I can say that the colors were there, which is why I set up the camera in the first place, but to the degree that I've captured and processed them accurately, it's anyone's guess.

Your feedback and honest critique are always welcome.
