This is Flandre Scarlet from the game Touhou 6: Embodiment of Scarlet Devil
She is a vampire with unusual wings and power ^q^) She's also a darling yandere <3
I tried playing around with the theme 'retro' and I made her a 1950's diner waitress serving floats.
Man, I am getting slower ; w;) Lol I suck at flowers. I am never doing that again.
