What do you say of this one?

Like Aleemi this is a downbeat write. Almost didactic this foretells doom, which is very much in the Apocalypse mood. Overall the poem works well. Normally I would be against using archaic language (thou) in a modern poem but in this case it works because of the biblical sound that you have created within the work. The only line I would suggest altering is, 'Flying the sand', perhaps, to, 'Of the flying sand' but this is a personal observation. This is your poem and it is excellent. Thanks for sharing that.
