NEED HELP FINDING SOURCE!

Hi, hello, I'm not sure if this is the right place for this, but I kinda need help with something.




I downloaded these (as well as a large number of other enemy sprites) a long while back to use in a game, but quickly lost the drive for it back then. Now I rekindled that spark, but completely forgot where I took these assets from. Can anyone help me find out who made these so I can credit them?
