My mind automatically pops to the old concept of purity springing forth from murky, darky depths of what most people consider disgusting trash. That would be the lotus blossom kicking in symbolism. Since your girl doesn't look particularly depraved, it's more subtle and gets me thinking on her psychological condition. I like the color scheme of her clothes, makes me think more subtlety.
i don't know if there's a link with what im gonna say now but still..: Both of the lotus and the carp are part of Buddhism symbols...xD let me say: i love the way you added the colors and the way you painted it
