I love the analogy the phrase "blood on their faces" presents.

Yes. this is amazing. yes.

This is fairly interesting however I feel that at places it is hard to read, you've set a fast shot pace but line 8 seems to disrupt the flow, and towards the end I'm not really sure what style of poetry you're going for. Perhaps you should try a specific style of poetry. this is only meant as friendly device to help you develop your writing. On the whole I kinda like it.
