Mermaid

At school I had the mood to draw something really great.
But I didn't know what to draw.
So the class' new students finaly realized of my drawing skills, and this girl really wanted me to do a mermaid which face looked like her.
I did the sketch, but I liked it so much that I decided to nankin-zise it and add a whole package of details that I didn't made in the sketch.
And this is the final result. Drawing was supposed to be given to her, but she didn't remember asking me at the end of the class.
