Harry Potter fanfiction fanart 

The Quindecimdei: Anna Moon (10/26, Painter Classic) Anna is an orphan who drifted from one place to another until getting the Hogwarts letter.
The Quindecimdei: Lisa Turpin (10/26Painter Classic) The friend closest to Anna - her dad is her only family, and she is Muggle-born. Maybe.
The Quindecimdei: Padma Patil (10/26, Painter Classic) Pavarti's twin, who excels at Potions. She has a fiery temper and such.
anna moon, ravenclaw girl by lilith true
The Quindecimdei: Ophelia Fawcett (10/26Painter Classic) She feels overshadowed by all her sisters and lives near the Weasleys; kind of a wuss.
Anna and Lisa  (11/27Painter Classic) 
A scene somewhere in Ch. 16 where Anna comforts Lisa.  I forget about what.
The Quindecimdei: Mandy Brocklehurst (10/26, Painter Classic) She wears glasses and has a pet owl; a bit of a tomboy, maybe?
Chaser Roger (1/20scan/Painter Classic) 
My attempt at action and perspective. I don't think his position has been specified in the books.
Lisa Redone (11/30, Painter Classic) 
I also learned in Ch. 16 that a lot of my physical characteristics were off, so here is a redone Lisa with slightly longer hair.
Old Anna Sketch (3/31, Painter Classic) 
An older drawing of Anna I did when I first got the tablet but found while cleaning out files. Done with the Sable brush feature, I think.
Mandy Redone (3/9, scan/Painter Classic) Here's correctly drawn Mandy with boyishly short hair and her pet owl, Hermes. The Anna Moon fanart really expanded at this point.
