Very cool! I love that they are recognizable but you threw your own style in too. It looks very nice.
I've used both as style studies before, but I really like your additions.
A few fun facts-
Popeye was a side character at first. Ham gravy and olive oyl were the main characters of the strip thimble theater. When Popeye was introduced, fans loved him. So it was him who got a show later on.
Betty boop was both a caricature of a real person, and her first appearance was as somewhat of an anthro poodle. Later designs changed to human.
