Cool idea. What's the material of the mask? It seems very reflective, you have some hotspots on it. You may be able to reduce those by putting tissue paper over your lightsource. I'd suggest not pointing the lightsource directly at the mask, but then you wouldn't get the shadow, would you! ;) If there is any way of not having the shadow from your hand holding the mask showing that would be a bonus. Not sure if that's doable though, so please ignore the comment if it wasn't.
very nice! I have no critique for improvement on this shot at all... i suppose that whatever is reflecting in the mask above the nose seems a bit strange but I do like this photo! = 9 - jmsetzler
There is a reflection in the mask which is barely visible yet distracting enough. Also the highlights being reflected off of the mask are blinding and could use some softening.
The irridescent colours of the mask are very beautiful. There isn't much emphasis on the shadow, but it's there, and the themes of masks and identity are interesting.
