Nice fade into the whiteness. Personal nit: the pupils look unbalanced in relation to one another. Partly the angle distorting the further eye, and possibly because each is receiving a slightly different amount of light. Makes her look annoyed, which I suppose could be considered a royal look ;-)
I'm not a member so I can't vote on member challenges. Instead, I look through the entries for images that make me stop clicking on to the next one. This is one of those images....
Really like the tonal range and transition from the subject to the edge. Hope it does well!
