Very dramatic photo. I don't know whether it's just me but I'm still seeing a sharpness issue, especially noticeable in a horizontal band between the first rock and the horizon (and also on the left of the picture). I had to look at the photo several times because I though my eyes were going funny and it made me feel a bit queazy. Is your paper sitting perfectly flat on the scanner? My scanner can scan film (transmissive) or prints (reflective). When switching to reflective I have to put a pressure plate thing on the inside of the scanner lid to push the print flat onto the glass. I have forgotten to do that sometimes and the scans are out of focus.
