First, I think that this did meet the challenge - albeit duck & lady are not two things that people normally combine.
Composition:
I think the crop is a little tight with regard to the duck. The placement of the subjects, however, is good and I like the use of mirrors. Not sure that the reflections/images through the glass duck help the image though.
Focus:
Okay - a bit soft. I think it could be a bit crisper to help support the subject matter.
Color:
Oversaturated IMHO. The tonal range is not that great and what is present looks unnatural.
Overall:
I think the image's score suffered because of a couple of things: the disparate nature of the two subjects and the oversaturated color. I think it has the potential to be much more, but technically the processing was a little too much.
I like the side mirror but I think the bottom mirror was alittle much and I feel if you experiment with the light and the composition more you will come out with a more pleasing photo.
An interesting little still life...I do like the reflection of the bust...overall it seems a little too "intense" color wise for my taste an maybe a different crop? The little duck needs a bit more breathing room perhaps? I really think this could be quite interesting as a black and white image.
A deeper DoF would have helped to place both items in focus. Softer, more diffused light would have helped to keep the reflections from becoming overexposed.
