I love the concept, the pickling. It reminds me of a similar concept I wrote about using butterfly nets to pin down memories of love. Its original and I like it.

However you jut need a quick punctuation check because currently one of your sections reads like this

"in all of time there is a need to preserve like a pickle"

Which I don't think is what you intended. I think you meant to have 'in all of time' in a insubordinate clause, so it would be

"Because there is only one of you,
in all of time,
there is a need to preserve, like a pickle,
the things that I love."

That's just my opinion and remember I'm no punctuation fiend so maybe ask your watchers for their thoughts before changing it, but I think thats how it should be.
