In my interpretation of this work, the woman in black and white is an evil person who is causing the girl in the mirror to fall to her death. Symbolically, the evil woman has to be in the sewer so the light of day does not fall on her. Unfortunately for her, some light gets in and the colorful butterfly, representing goodness, will haunt her conscience forever. The rats, which represent evil, love the evil woman and will bring her down to their size eventually. This is a great photo manipulation especially with the tunnel's perspective drawing all attention to the evil woman and the mirror. The light from above is fantastic. I would only suggest that when pasting in the objects, that the edges be narrowly selected and then the Gaussian blur tool be used at a setting of 0.7 to meld the cut surfaces. It takes a bit of time to do this, but the results would make it worth it. This would help enhance the illusion that it was actually all taken with one camera shot. This was excellent work overall.
