A Piece of Glass:

[Philatone]

hey billy

Translucent green, it held no sparkle;...I was ok with "it"
edges smooth from pounding waves....as is, it sounds as though the glass does the "pounding". I think "smoothed by" would strengthen the effect, with "by" showing the agent.
It lay there on the ebb, a memory....period doesn't feel necessary; I think switching the line (A memory, it lay there on the ebb) also gives the image more immediacy, though I see it is being used for a pattern.
Waiting for life, waiting, waiting....I get the effect, but am not convinced all the "waiting"s are necessary

Along with empty razor shells....period needed?
A cuttlefish bone and lots of little ones;...everything was nicely specific until "lots of little ones"; it felt a bit out of place for me
miniature ice cream cones, memories-- ...this is entirely personal taste: I get the idea of "miniature ice cream cones", but the wording isn't my favorite. playing with something besides "miniature" may help, as "ice cream cones" is difficult enough to replace (although, maybe "sugar cones"?)
Waiting for life, waiting, waiting.

Treasures washed in tide pools ...again, after such specificity, "treasures" felt a little flat
where crabs no bigger than a finger nail
scurried like Spanish dancers. Memories;...I like the line and the sentiments. however, the "no bigger than a finger nail" is a bit clunky
Waiting for life, waiting, waiting.

The keepsake kept, is still as dull
as when it lay upon the Southport sands ...don't think you need the article "the"
Now it's worn around my neck....in some ways, this could have been tied to the first line and led to a more concise stanza (The keepsake kept around my neck/ is still as dull...). i like the tie-in to the opening
A memory--

I enjoyed the calm, reflective nature of this. Overall, I liked the images and words used to convey them, but I did get snagged at several spots. A lot of times, it involved those nouns that take two words to convey (fingernail, ice cream) that are difficult to substitute, but still are a bit of a burden to get over.
