Character Study: Sheena Queen of the Jungle

I made a post earlier that I was planning a new comic project using 7 public domain characters. I accidentally listed one as Shannah the She-Devil which is NOT a public domain figure. What I meant to say was "Sheena, Queen of the Jungle." Which as you can tell by comparing them side by side are totally different characters... ?

I certainly wouldn't want to infringe on someone else's copyright and find myself in legal trouble...
