The mood is straight forward in the photo the photographer perfectly caught all the expressions at the right time. The anticipation felt is strong and the framing of the crowd on the side of the room causes he mood to become stronger.
Assuming that the girl has died, simply by the way she is laying. This is a photo where you feel the sadness of the situation as well as the joy of believe that she is in a better place(represented by the white lace). Not having the girls face dead center helped the composure of the photo giving its emotions more strength.
Artistically this photo is amazing. The way the pillars frame the plane, the bold blue sky and white puffy clouds behind the plane. The architecture simply does so much for the photo.
