So there is a lot of debate out there now that we have cameras that can handle wide dynamic range available. One of the lines of thought is just because you can extract shadow detail, doesn't mean you should. Your two images come to mind with this regard. Part of me says the darks are too heavy handed, drops to pure black way too fast. But these also remind me of some shots I took with my older canon gear back in the day, and I was super happy with them.
I guess it depends on how you were to present these. They are super high contrast - HDR-ish. Printed on metal, they would be pretty cool... as in the highlights would just jump off the page. On the other thing, on a matte surface, the contrast might not work as well.
If it were me, today, I would look to bring back a little more detail. Just a hint, to add curiosity, detail, subtleness back in. But were nit picking here. I'ld be happy sharing them. I am there are perfectionist who could find more issues. That isn't me. Im more a big picture guy, than a pixel peeper.
Thanks for sharing
