Wispy Wistfulness

Taken from the observation platform of the Jangfraujoch Sphinx Observatory at a freezing minus 7 degrees Celsius, there was certainly no time to be in a wistful mood then!

When I finally post-processed the photo back home, my initial instinct was to boost up the saturation of the blue sky a fair bit. CY thought that the original muted colours was more appropriate for the wistful-looking mood of this shot though; the boosted colours brightened up the mood too much. I have decided thus to stick with the duller colours from the original in keeping with title of this shot. What do you think?
