Beginning of sin

I see a story here: She's kinda touching her groin.. so... by "beginning of sin," does this mean "first time jilling off"? I'm merely asking. If that's the case, I interpret her glancing over her shoulder as not wanting to get caught, as is so very prone to happening with females, and the being under water is a sign that she's immersed in a false darker world filled with not being able to breathe and sin and such, and her sprouting a fin is representative of her transformation into (beginning of) one of the creatures of her new world, a sexual sinister (wet) world, and she won't be able to breathe on land and thus can't return (to innocence).
Oh noes, her heart is floating away! ..I think.
Note that I'm not Christian; I'm just interpretting this piece and what is exactly occuring. I'm not sure if I got the story right. Anyways, it's awesome how somebody can get stories from this pic.

Great job making the fins and tail look transparent, although they sorta kinda lack detail. Also nice job on the hair.
Negative points from me, though, for using or photoshopping an underweight model; I'm assuming she's slightly underweight by the width of her upper arms and the steep indents on her shoulder.. or maybe those indents are actually shadow. I'm not a thin-hater; I just think that arm's too thin and it bugs me 'cause DA photographers often use underweight models. I think her face is very pretty, though.
