Before the Sea

I do agree with Alcuin about the wordiness of the first part, and also the great impact of the last few lines.  Here's something of what I'd do with it to render it a bit more concise, perhaps it might help you:

He walks away from where he'd been

In my arms, my kisses tasting summer in his hair

New treasures await his delight;

His simple pail a pirate's hoard.

He pauses, eyes sweeping the broadness of the sea -

A speck before the vastness of worlds,

Nexus of adventures unfathomed.

Little one, the sea is before you.

The sea is within you.

The sea seeps from my eyes.

Now obviously this is just my rendering and of course it's entirely up to you should you wish to change any of this.
