What makes a good poem?

I promise, the long pause between posts will end.

Anyway, I wrote a poem recently, and this is the result:

i love you within the
deepest depths of my heart

Which shattered like a silence interrupted
when you said forever we should part

The sun is dull, compared to your warmth
All the fireworks, the explosives lit in merry delight
become mere flashes in your presence

a mug of the warmest coco, a fire burning so powerfully
Smoke masks your breath for a moment

Becomes icy as the frost lining my bedroom window
When memories of you pop suddenly inside my deepest thoughts

The ticklish sensation of your soft lips clashing against mine, rough and chopy,
Yet you didn't seem to mind.
Our first kiss seems it happened only seconds from now

You never sent me flowers, sonnets, chocolates with cherry centers,
Never told me you loved me between each subtle embrace

I could tell each time you acted kindly--you were respectful, beautiful, every kid of "ful" in the world, is what you were


"Nothing could compare"------that's the ballad i'd have recited if you'd fit my well-crafted description

You heartless pig.

I hope you dream of your cruelties,
And wake up in a mess of tears, an ocean of blankets, pillows, sweat
SCREAMING MY NAME

I showed it to my dad, and the question he asked was "who is this about?" I told him that it wasn't about anyone in particular, that couldn't poets write about fantasy events? "Poets have to include the characters in fantasies as well." So after that, i began to think about what made a poet stand out. Does a poem really have to include the characters? does it have to rhyme, or use complicated words to make it sound as if you were writing something better than Shakespeare? What do you think a poem needs? What do you think of mine?
