Well, I'm working with an old shot (about 2 years old) so reshooting isn't really an option I'm looking at here (I was just browsing old photos to find which ones I wanted to play with). But I did play around with it some more using the clone stamp and the eraser to achieve a better looking product:
I've also decided to do a few variations (just a little playing has turned into a whole art project)
I have another one that's just those two side by side (angel on left and devil on right), and I'm working on another variation that has those two in the top half and in the bottom half will be a picture of me looking thoughtful (probably going to have an obligatory chin scratching) and looking up with the Earth in the background... but I'm waiting for my lazy roommate to get his butt out of bed to get the "me looking thoughtful" shot taken.
