Ian, this is a dramatic look at this glacier. I do find myself wishing for a bit more room at the bottom and noticing the strong change in color and luminosity across the sky. The sky looks like you were using a polarizer, although it’s possible that there was that much change as you turned closer to the sun. The penguins near the left edge are a fun surprise.
Ian: My thoughts pretty much echo @Mark_Seaver but I really envy you the experience. My only other nit is that you should have instructed the penguin to look into the frame and not out of it . Hard to find good models these days. Beautiful scene nicely rendered. >=))>
An interesting scene and a great look at the glacier, Ian. As noted, the penguins are a nice treat after you see them. I’d be tempted to look at bringing up the shadows a bit to see if you can make the darker areas contribute more to the image, though that might be partly the limitation of scale we run into viewing a pano on a computer screen.
