Can someone with some literary grounding/understanding analyse my poem?

I have written this poem in the hope of entering it for the SDP national poetry competition. I am happy with it, but I would like the opinions of some other people before I produce a final draft. In particular, I would like for some analyses, just to show whether I have succeeded in portraying what I feel to be a very specific message in the poem strongly enough for others to find it, and some opinions as to whether this really is a piece that could really be considered a piece of "literature". Thank you all in advance, and wish me luck for the competition,

Stephen

the poem is below:

The saddest thing I have ever drawn

The saddest thing I have ever drawn

Not well, not perfect

But an effort to the furthest reach

Of my shaking hands

And blurry eyes

A wedding dress in red and

White? Sweet rebellion,

Forever trapped in a childlike innocence

Never the stain'd white but still

A softening beauty, sun hot embers cooling to black

To stone

To the tall proud forever rock

Immaculate

Uncrying

Unmoving

Smooth drifts of forever like you dancing in my brain

Ethereal and wan amongst

Firing neurons, and dying cells

Slowly growing in me

Emptiness in one dull section in the back corner ,

My brain already tensing round the pulsing mass

Ready to push in and fill the gap

Like the corner of my world

A ten second walk down around

And so my head is my world

And there will be the gap

And the earth will be cold and bleak

And static; refusing to press into

The ugly black hole

and make you never were

A void of dirty broken was, and could have been.

A hole in the shape

Of silly dancing

And union

And Rich heavy folds of a time that would never be

Draped around a faceless air

The saddest thing

I have ever drawn

A dress

In red

And white
