This is so eye catching!!
They way you hold you hand makes the watcher look directly at the face. The hand is also showing the emotion in the picture.
The facial expression is also good. Just the way you look upon the watcher makes them wonder, why is she showing this face and who or what is it meant for?
Nice work on the costume and background. It makes the watcher look more to the face, then to the objects around you. The white background and white clothing really brings out the expression of the picture.
Nice work on the posture, since this girl is supposed to be a queen, the body most also be presented as a queen. It makes the viewer really think that this person is a queen.
In all, nice work!! Keep it up.
