I've been having trouble with this poem for a little while now. This is maybe the second or third draft, and it still seems rough and awkward to me. I've attempted to write it with no punctuation beyond a few commas, so that the sentences aren't very clear-cut. (I've tried to do this before, and this attempt is the most successful I've ever been, I think. I just like to experiment with sentence structures and punctuation.) Anyway, I'd love a different pair of eyes to look at this and tell me what they think. What major problems do you see here? Do bad word choices stand out to you? Do I need to change the tone? I'm very grateful for any help at all. :)

No Climbing

she pulled herself up past the “No Climbing” sign,
scraping white soles on a rough, rich bark

stepping through the branches, she was Cinderella
climbing a palace staircase

at the top, everything was falling up
northeast and to the left, and down, down

everything was falling away

she felt her cells tug apart
gently, as if a child was exploring
by pulling and prodding

watching her arms grain into sand
she developed a newfound trust in signs
