You wrote a great poem about an open door in a field.
Grammar and spelling are good and don't distract me.
A genres could be chosen.
I found myself genuinely enjoying your poem and eagerly reading to find where the door led. Was it a magic doorway or just a mysterious relic? I kept reading to find out.
Well done writing a good form. I don't know the name of this form but I like how the initial line is carried through the poem.
Write on! My review has been submitted for consideration in "Good Deeds Get CASH!" .
