My hats off to you for taking on the challenge of writing Luna's character. Not many authors are up to the challenge as she is both quite eccentric and complex.
Your writing flows well and your poetic capture of Luna's character is spot on. I do believe that the line "the laughter of the flowers as the wind romped..." is one of the finest desciptors I've ever had the pleasure to read!!
Do keep writing about this couple as they have been one of my most favored pairings and there is not nearly enough fics about them.
