I liked the flow... HOWEVER... there was not enough information for me to interpret. Who was this warrior who went to war? Why the smell of fresh blood make the enemies fall back?
However DARK this poem may sound. It still needs more information so the READER can interpret the poem.
Still, this is your 5th poem. Hell better than my first 15. So I say its a very good poem.
So I say, well done mate!
Next time, put your head in the dictionary and thesaraus and learn new words to spice up your poems mate!
