You should be able to guess what pairing created this offspring.
The contest was basically to design the offspring of a Naruto couple. I thought this would be a cute pairing, because I don't know that I've ever seen fanart of Sasuke and Temari together. I tried to recreate the street in the abandoned Uchiha town, the one Sasuke is running down when he sees everyone dead. So I figure she is reflecting on a past that she knows nothing about.
As for her age, she's probably about 14-15 and yes Sasuke is very proud to announce that she possesses the Sharingan capabilities.
