I second what ItcheSrulik said.
As soon as you give it to someone else, it isn’t their personal prayer. You fail to mention, did any of these Rabbonim who know well suggest you publicize it? Did they even agree that you should attempt to publicize it? Ask any of Rav Stein Shelitas talmidim if he felt you should publicize your compositions, as heart-warming as they may be.
