As a point of order, in my experience of masques and carnivale and the like, glasses and masks are hardly unrelated. Whatever; good detailing and light on the mask - and it's a beautiful object too - but your inclusion of the glass seems entirely arbitrary: it's appears oriented differently, weakly placed compositionally - to the extent that one might believe, if told, that it was cropped out of a different photograph; and that was the challenge, I think - to make photographic sense out of the combination. I don't really think you've succeeded - it needs the feeling that these two unrelated objects are at least in the same light space, or something - but I like the mask very much.
This would be so much better without the glass, but then it probably wouldn't meet the challenge. :-) Incredible mask, very well lit. The glass, however, just doesn't make sense photographically.
Splendid mask, and brilliantly positioned. The glass isn't up to par with the mask, but still the mask is so spectacular that you almost don't care about the glass. Fabulous lighting and coloration. Black background is very effective with this subject. Well done.
