Very beautiful work, Jim! The grain of the wood at the top of the arch seems to flow and merge right into the texture of the clouds. Excellent work with the focus stacking, too!
Thanks for all the comments guys. This was a cool cloudy day (snowed the day before) so I was thinking B&W as I snapped most of my pictures. Found this log at the end of the day near the parking lot.
Overall nice photo, I really like the composition. I like the processing on the bottom 2/3rd of the photo. The top feels overly darkened and there seems to be a halo on the top of the log. The detail in the log and the rocks is nice.
