reaching for a place to pivot

In S1L4, the "there is" dilutes the effectiveness of the line. Generally, "there is, there are" etc. should be avoided in poetry. Also, I don't think S2 has the power it should. I feel like it and S3 should be one stanza. In S3, what do you think about eliminating the "at", turning the "cobblestone" into a verb?

Finally, I thought S4 by far the best. (BTW, "edged" has a typo.) It echoes S1, but with more passion.
