Hi,
Thank you for sharing this. I am a newbie as well, but have been to many a poetry workshop. ;)There is a lot of emotion and a dark, deep feeling that holds on throughout this peice. The imagery is thick. My favorite lines are " Stop demanding a central theme from a season that isn’t done shedding its final leaves" and "I am a wave fighting the tides of grief."
There is difficulty seeing the main theme/idea of the poem. Is the speaker the wave? What helps me convey clearer meaning in my poems during my revision stage is to take out lines /phrases/words that repeat or are unnecessary if the idea is implied elsewhere. I am guessing it is sorrow? My first drafts are often similar to your poem. It comes out as ramblings, but if you take a fine toothed comb through it after letting it set a week or so, you find some real gems. Those are what the reader wants! Paul McCartney once said "Less is more" and I have seen this work best in poetry. If you don't mind, take a look at my suggestions below for the 1st stanza. I included line breaks to "break up" the heaviness of the poem and to show off the gems:
"Today I start at my end.
I am a wave fighting the tides of grief.
Whose turn is it to mourn today?
What shift will the kaleidoscope of despair turn to,
to tease with the shimmering slivers of colored glass,
..."
I think you have a lot to work with here! It's better to have to much than too little. Sometimes, I don't even know what my poems are about when they first come out all willy- nilly, but after trimming the fat, (repetitions or things already implied in the poem), a clearer picture starts to emerge. I do this same revision over and over until it makes more sense to me. I hope that this helps you out. Let me know if you need more suggestions.
