This was a tough round I think. Personally, when I think of 'impressions' I think of Impressionism, which would be really tough to do with unmodified photography. The imprecision of Impressionism just isn't well served by that medium.
I really liked ysrh's composition (what a cool room!) and kate's landscape choice, but I went with Bearlove because it reminded me of Mélièz's classic film Le Voyage Dans La Lune. Particularly how their rocket flew up to the moon, and impaled the 'man' on the moon right in the eye.
