Nice glittery shine, but the photo needs something more. The beads hanging around a womans neck, with her hand holding them, or unbuttoned collar, or something like that would give you a better story, and give the viewer a subject focus.
This is a hard subject to photograph what with all the different reflections. There's no central point of interest and too many reflective highlights here.
I am not sure this is an HDR shot. I dont see anything but a snapshot and in reality it hurts my eyes to look at it due to the relfections and the lack of focus. Keep shooting and entering, listen to the comments you get and learn. Good luck.
diffuser my friend, diffuser. HDR is still going to have a hard time fixing those specular highlights. also, try to think of a main subject to create within the chaos. nothing stands out here.
