Collaboration!

Started Nathans collaboration work today, initially I thought I was doing Castiels expressions, but for me to get used to liliths features for the in situ I have to do, I decided to do her expressions. This is what I have so far, I tried to mimic Naths style of quite realistic, and I thought I'd have a go at drawing straight in to photoshop, something I'm not used to, so here they are so far.
