Today looking at lot of Pinterst I found a ton of "double exposures" "stacked images" or "image composites" whatever you want to call it, so I gave it a try, first few were bad! like, not even worth talking about. but then I got the hang of what two photos could work well with on another. Takes some time and practice. One day I'll master it. Here are a few of my later (worth posting) tries.
This one with a touch of color, to add in my own twist :)
