"Collected in glass jars these tears
could now tell a history"
** Those lines are broken up in the wrong area. Maybe try; [Collected in glass jars,
these tears could now tell history.]
Other than that minor thing there's nothing wrong, at all with this poem. Well, other than the entire punctuation thing that I explained before. But, once again it's not THAT big of deal it would just give it that "wow! flow!" type thing. But, it's still a good poem without the punctuation.
