It could really work well I think!
However, to add to the mysterious sense of this moment - and most importantly to convey it to a random audience who see only the picture, and don’t know anything about the story surrounding it - maybe you should consider keeping some typically antarctic features in the background somehow… maybe there could be some elevated terrain in the background that still looks snowy/icy… that would even increase the contrast of the image in a good way - the buildings and vegetation being so much more out of place and enigmatic.
