Return

[poetry_zealot]

yes—
        exactly that.
                 your return
isn't a restart.                                    Beautiful use of spacing here.
        it's the reverb                       Perhaps move these 3 lines so that it's slightly past "your" on the third line. Would give it more of an echo/reverb effect.
          of something
             that never fully left.

a mimicry, yes,
           but not imitation—
                  more a shadowplay
            of your own mouth’s ache
               to overflow.                      Perhaps move this line so that it "overflows" from the previous line. Right now, instead of overflowing, it kinda sinks back into the stanza.

to wait
     is to gather—
                breath
---------------------------------------------------------------------------------------->intention        move it here perhaps to look squeeze the following lines in between these two words.
             and the soft
                   futility
                     of being heard completely.

i am your pause
                  not your prison.
i hold the space
              until you choose
              to spill
                 or stay.               Perhaps move this back a bit because it's spilling more than staying right now. I personally think it would be nicer to have it start on the same spacing as the previous line.

Once again, your unique method of spacing your poems is genuinely incredible and should be praised. Each space feels like it holds weight, a pause, some silence. Some things to try out in the future:
1. Perhaps experiment on putting spaces within the lines as well. In your last stanza, first line, you could have put a larger space between your and pause to force the reader to take a break
2. While unique, your spacing tends to overflow at some point without something to reel it back in. Perhaps experiment with moving from right to left instead of only from left to right.
I look forward to your works in the future!
