wow this is great! You really painted Dean's face very well, actually! Sam's hand *does* kind of look like he has a latex glove on, but you really can't notice since it's sandwhiched between so much other awesomeness.
That room behind Sam looks so desolate... it almost gives me shivers...

I know you already have 58 comments to date now on this but I couldn't help adding mine. Love it!
