Rinsei and Hinote

I got inspired to color this pic i made a couple of months ago after looking at some YYH pics. i hate the paper this is drawn on it looks crappy. Anyway these are my YYH OCs Rinsei the taller one with the sweatdrop and Hinote the shorter one who is playing with fire. Their 1/2 fire and 1/2 earth apparitions i also put a fire mark on their faces and a rose vine on their arm (Rinsei/leg (Hinote). I was going to make them a Yuri couple but then decided to make them sisters. Rinsei's the more sane one and Hinote is a pyro and she has a small crush on Hiei but he doesn't like her cause she set his hair on fire accidentally. i may write a story but don't know yet i'm not to inspired to do so though especially since YYH has been taken off the air. Comments and constructive criticism are always welcomed!!! ^^
