This is fantastic! How did you achieve this? I'm enjoying playing with different techniques right now too. This inspires me to try double exposures too!
@kartia Thanks! I cheated :-) I found out that my Olympus E-M10 II has a dedicated "double exposure" setting. Not only does it allow you to take two exposures in the same frame it will even display the first exposure on the screen while you take the second one so you can see how everything will work out. I don't know if this is an Olympus only function or if something similar exists in other cameras. I can't remember seeing it in my Canon cameras.
