Wow, this was a wonderfully detailed picture! It really is a very unique scenario. I don't know why a giant beetle is caring for a monkey. I didn't even notice those were giant maggots below! Or maybe that's just a really small monkey. That is pretty creepy.
You got the details down wonderfully. I don't know what the "marm" part means. I think those bluish green things are mushrooms. It's weird to see such innocence in something so, well, unattractive. It's a very impressive picture.
