A well done, powerfully emotive photo...just don't feel it fits the challenge all that well since it actually has a person rather than a human-like inanimate object.
I think you are using another definition of Personification (and in that light, it is a good interpretation), but the challenge was going for the other way (inanimate object given human characteristics).
You convey a good mood in this picture, but IMO it does not meet the challenge "Take a photo of something non-human-looking but yet still shows human characteristics or evokes a human feeling." This is definitely human looking.
Really like the subdued feeling this has. I like the model sitting almost in the shadows and jet the windows lighting the pillars gives it a feeling of hope at the same time. Excellent job and well done!! "10"
I guess this challenge will elicit a lot of discussion - the description said inanimate object and centred on one meaning of personification - I agree with you but does it fit the challenge as set out by the organisers? Nice shot.
