Hello Mick,
what your poem says to me is that you can pin-point moments of significance in your life and make them rhyme. I feel no sense of why they are significant to you, nor why you choose to put them into a poem. I think you probably have the skeleton of a good poem there, but you need to think about what a reader is going to get from it in order to flesh it out. To me its just a list of irrelevant images, most of which are not unique to you and those which are rarer, well, they're not unique either. What would make it unique is if you told us a little bit more about how they made you feel, other than just 'lucky'. In fact, repeating that phrase over and over makes the whole poem seem a bit jangly and detracts from what are obviously intended to be serene and sacred moments.
Hope this has been helpful to you, be not deterred, Bryn.
