What is you opinion of this poem i wrote?

Sirens are known for their lovely voices, yet you seem to make them sound unpleasant. In my opinion, the tenth line "they seem to think we should worship them" sounds clunky. You say she has no power over you, yet you state "no longer will i let you have that power". As if you came under her influence and are now leaving it. It also seems overly degrading when you say "vapid little ". I think it would more appropriate to mention her actions with vicious and decisive words first. I like your use of simile in lines one and two; furthermore, it makes me think you purposely mentioned "shrill voices" to contrast the inner and outer beauty of these temptresses or sirens. I think I get the overall message, but it could use a little cleaning up.
