What do you guys think? Have you seen an icon using the same image in this same style before?

I also skimmed through my hoard of icons to see if I could find anything. Here are some that are reminicent just for fun:

I'm not concerned about "inspired" as much as I am the possibility that I've just ripped someone off... I mean, I look at that icon and I feel like I've seen it before. It's scary, tbh.
