Very nice. Rhea hides Zeus (myths say she disguises him as a rock), and Zeus grows up and defeats Cronus (who did eat his children) releasing his godly siblings and ascends as king of the gods. I love the Mount Olympus rendition too.
That's... slightly true. He did use the scythe to chop him in thousand pieces, but as any god or titan, he was immortal. However, now harmless since his parts were scattered in the deepest trenches of Tartarus.
