Linfa chibi

I'd scrap this, only I like the actual drawing and I want some feedback on drawing on black paper. ^_^ My normal sketchbook is at the bottom of a box (drawn-out bedroom renovation) so I decided to go on black paper for once.

So yeah. What's a good way to shade on black paper? =S Just shade the very dark shadows, or anything darkish, or shade everything that's supposed to be white, or what? I know I've seen the Fullmetal Alchemist manga-ka use lines rather than actual shading which looked cool, but all of those volumes of manga are also at the bottom of a box. XD;;

Anyway, Linfa-chan. She's a very elite and snobby angel who just needs a big hug. This is to celebrate me getting the final volume of Stray Little Devil yesterday.
