Thanks! It isnt that hard to do really. First I made a selfie via the timer, with the camera set above my head on the bathroom closet with the shower curtain rod in/before my hands/face. Second I made the capture with the can sorta how I had envisioned the final composition, tinkered with both shots and made a few different captures until I had two that matched in wb and sharpness. Then downsized the bathroom picture until the size of my head fitted the can opening (somewhat convincingly). And then added the downsized selfie to the can image as an extra layer behind the can layer after which I aligned them exactly with my head behind the can opening (with the can layer at 50% opacity/see through) and then erased the pixels in front of the selfie in such a way that my hands seemed to be around the edge of the can instead of the curtain rod.
Took me quite some time to do it but it still puts a smile on my face so was worth all the tinkering I guess đ
Bad habits yes, at the time I had multiple as I smoked an entire package of cigarettes every day, drank multiple cans of coke and ate away everything to taste but eventually I traded it all in for fruit/veggies, sports and clean air after I started to loose my health because of it.
