To be honest, I'm not a fan of "Tarzan". I don't mind the nudity and I like your depiction of Kaza and Gwenna. What I don't care for is the strange voodoo like elements like Mr. Walking Skeleton here. I'd be more likely to read if they battled more ordinary villains like the empirical oppressors that want to take over the land. I'd also like to see more realistic depictions of the Africans who weren't all so voodoo-rific.
The Skull is not voodoo, but an old villain taken from the Golden Age of comics. The whole project is a fun homage on old tropes and comic books, and personally I love the super-villains, Sci-Fi and supernatural elements. Thankfully, not too much voodoo, though ;-P
in panel 2, that should be "within an hour"
