Cobra X Angel lineart

I noticed that roughly most of the guilds with dragon slayers in it are always accompanied with a stellar spirit mage... coincidence? Maybe not... we have Natsu and Lucy, Cobra and Angel, and now Sting and Yukino... ^_^

So here's Cobra X Angel (Not sure wether they like each other but somehow to me, they are the evil version pairing of NaLu) ^_^
