The way this picture has been executed is brilliant.
First of all, your costume is very stylish and the accessories on your neck and hair on top of that are spot on. If you made the dress yourself, I can only say "vow". In any case, I do admire the effort here!
As for the picture, I like the composition, but what really makes this picture work for me is that it sets my mind wander. Although physically present, you appear to be absentminded, looking deep in thoughts past the camera/company you have, leaving the viewer wondering what it could be. And, hoping someone would release the Pause-button to see what happens next and find out more about it.
