There's just enough here to show an unclear scene. Only one thing I would omit: "from willful hand," because it's repeat as far as I can tell. You might want to let us in on a little more of what's going on.

the last line needs working on i think ..it does lighten the intensity but is that intentional? does she want to touch him? or was he way out of order?

deepest pockets sounds forced. i think willful hand needs to be plural. the rest works pretty well i think.

Not sure why you started with "While"--it reads as "while hanging there . . . they sought the shelter," which seems off, odd. Would work if you just started with "Hanging in midair, her fingers startled still . . . curled like cowards . . ." I do like aspects of this--I like the sharp focus on the image of hands, the way you convey the story completely through what the hands are doing (reminds me a little bit of the scene in Hitchcock's "Notorious" where Ingrid Bergman has stolen her husband's wine cellar key, and there's a terrifying moment where you think she's going to get caught as he goes to kiss her palm, and all the tension and emotion is conveyed by a long shot of her hand holding the key, closing 'round the key, a fist behind her back and, finally, the open, keyless palm he deposits a kiss into). I'm a little confused by the syntax of this--hard to figure out whose fingers, whose willful hand. If you could clean up the narrative a bit, think you'd have a really effective poem.
