how?

Poetry doesn't always have to rhyme, none of what i write does.

To concentrate on one theme in particular i find it useful to use imagery, and focus just on that imagery...I.e. describing somebody as a rose etc.

The main thing is not to let yourself write anything else, but it's good to have themes which mix together aslong as it's not confused.

If you progressed the poem, the person woke up after the dream.

If you jumped from completly different thing to another (Unless there is a poetic device you are using) is strange, but then for all i know that could be really amazing.

problem with poetry, just like art - it's subjective...i can't tell you something is a good idea or a bad idea, just tell you how i personally like poems.

Well, look through it - try to maybe take a section and then re-work it to become a individual poem?

In my opinion, leave it the way it is. Unless, it makes no sense at all. All people write in differant ways, like a fingerprint, no two people are exactly alike. Write from the heart, let your hand do the talking, if it needs revised after, so be it. Don't change anything to fit a "poetry template". Originality is one of the keys to being a great writer.

Poems don't have to rhyme! As for jumping from topic to topic...it could make for an interesting poem! As long as it's a smooth transition within the poem! Or as Sean said you could just pick a piece of the poem and elaborate making it an individual poem! Good luck~Holly
