Do you mean, a 'slender' grip on life, or perhaps 'slender' reeds. Whichever, I'm a bit doubtful about the purple tinge (although it adds a bit of interest) and I think this is a bit too messy. I don't mean that ina derogatory sense, just that there is too much rather untidy detail.. a little bit of 'order' might have helped . Nevertheless, it has something.
