Want to comment on an attempt at a poem?

I’m no poet, but I like to try to write things in my free time. I’ve seen people give and get contructive criticism here and was wondering if I could get some of the action…

I lie on my back and trace with my fingers
The swollen remnants of a sculpted memory

Where once I felt form, now come slow moving waves
Giving in to the motions my hand commands

There’s now that once-known delay when I jump
The jolt gravity delivers once more given twice

…I had been free.
I had been, I lost it
Now trapped I’m swimming in all I’ve reacquired

I’m searching, searching, reaching for shore
Or for air
A break in the surface
A shallowing of the deep

I had it, I felt it

But now buried
It only hides

Please feel free to attack it! : ) I never get critiques so I have no idea how anything I attempt comes off on anyone.
I welcome anything you want to say.
