How about these...

(second version snipped)
Honest opinion. I like the freestyle starfish. Remove the coin.
Thank you, shijilal, for the movement, the figure that agitates.
I get a strong sense of a human/starfish, although the double lines confuse me a little, and might not scale well to a small version.
Do you want to 'simplify' it a little?
I also would leave out the surrounding 'coin' additions.
