This oddly made me think of a book I read a few years ago. I don`t remember the author but the title was Fairy Bones. This made me think of the main character and a hardship that she had to go through to find her little sister. Fairies had used their magic to make plants kill people and when her little sister was born with magic their father left her out to die and then the main character started finding out she was magic too about the time she was hitting puberty. Its a really interesting book.
This picture is really cool. I think that if you had made her eyes a darker color though it would have looked better. Other than that I love the expression she has and as always I just love your use of highlights and just your talent.
