This feels to me like an early draft of a lyric, but I think it's because English is not your first language. Am I right?
I have two questions for you.
1. I see you have just barely signed up as a member of the forum. What do you hope to gain from your membership here? I'm wondering if you're planning to stick around and participate fully in the activities (by reading and following the guidelines, for instance), or if you're primarily interested in polishing this particular lyric?
2. What type of feedback do you hope to get for this lyric? Are you mainly interested in how it's perceived artistically? Or are you looking for advice on how to improve the language usage (grammar, flow of wording, etc)? Or something else or a combination?
Then, regarding the lyric, I have one question right away. What feeling or idea are you trying to get across with the phrase "plastic heart"?
Sincerely,
Vicki
