Chris this is a nice idea! IMO a few things could bring this one from nice to amazing: white balance, a slightly different composition, shadows (even if they have a certain appeal to me). Most of this could be done in the editing stage. I hope these advices can be useful for you :)
Extreme healing powers to bring back the dead is indeed super. I think the 'double' exposure showing the dead come back to life was done well. The idea is good and solid it is just that I think that more attention to detail would improve the shot more. First off the deep shadows are rather odd and distracting (and given the positions of the healer the hands of the risen dead would not be on the wall that far back because the healer would block that shadow). While taking the shot, I would recommend moving the subject/objects several feet away from wall so that you do not get those deep shadows. My second critique is the possibility of the deceased staying perfectly flat on top of the thin top edge of the sofa is highly unlikely. Half on and half off would be possible but much more likely the deceased would have fallen off. As a friend would say to me at this point, "shut up, it's magic!":-) But magic cannot explain everything and the better you ground your supernatural with some reality the better the believability will be. Lastly, I think the position of the healer's hand should be just a little higher to rest directly over where the viewers will instantly recognize as the heart. The position of the hand as it is now is not near the heart and if it was the idea of a deliverance of the spark of life would be stronger.
Oh, and btw, I do like the addition of the old style broom as that I feel it is a subtle reference to the broom scene in the classic Disney's Sorcerer's Apprentice:-)
