Where is the remote?
Valid pointers there. It was shot within an airport. I remember that there were a couple of eating joints/bars on the side of the lounge where we were sitting. Must be some play of artificial lights that were caught . The light was mighty dim too hence even at ISO 1000 & f2 I only got 1/60 ss.1. First and foremost thing that has caught my attention from a critique's perspective is the color of the hair. Certain strands look blue to me.
2. The crop - just a bit tighter towards the left and eliminate some space above the head too.
3. The exposure seems almost perfect for ambient light, perhaps a 1/3 stop more would make it more vibrant. The skin tone is a bit pale, especially with a shade of yellow to the right cheek/nose.
I can't find anything negative. The above comments were just for the sake of critique. The picture is indeed wonderful for a SOOC image.
