Supernatural OC Designs

I've gotten really into the tv show Supernatural over the past couple of months, so of course OC ideas started forming lol These are some designs that I really like, but may or may not stick with. The girl on the the left is a medium, and the girl on the right is her younger sister who died not very long ago, but has yet to move on. I haven't decided for sure on names or personalities yet, so suggestions are welcome!
