Pelican Double Exposure

I photographed some pelicans late last year in St. Mary's County, and made some double exposures by mistake.  I had been playing with double exposures before I went out to photograph the pelicans.  That should teach me to reset my camera!  A few images were kind of interesting.  I decided to play with the image a little to see if I could line it up a little better.  It is not perfect, but it created an interesting image.  Not too bad, since I haven't done this much.  I am sure there is a more exact way of lining up the images with rulers and such, but it wasn't easy to try to line up the beak and get them made as similar sizes, while still making sure the wings didn't end up outside the frame.  Sometimes the best way to learn is by giving it a try.  Comments are welcome.
