Post your poem here. I will rank it and give as much critique as I think it is worth or as I am able, using the all time masters as a standard. By that standard even a 1 is not so bad. But a 10 means your poem could sneak into an anthology of Greatest English poems. An 8 would probably get you into an anthology of modern greats. A 6 is a solid poem, it just does not sneak into an anthology of greats, yet is in the neighborhood of being good enough for publishing in small magazines or local journals. As low as 4 might be enough for this. Remember, our standard is an all time great poem, which seems hardly fair at first. The fair part is that you never really have to feel bad when you understand your poem has been judged against the likes of Jenny Kissed Me or Sailing To Byzantium.
I do not see any actual contest with the poetry contests, so I think a ranking for individual poems is better than nothing.
