Lovely scene this. I like the imagery you use; the sunflower self, the pool of sunlight and that very favorite, sunkissed. Sun is a very good thing indeed.
But.. personally I loved the last stanza as it was, with that comma instead of a period. It leaves many ways open on how to read it and gave it a lazy rhythm that I have a hard time finding anywhere else. Possibly because I'm missing punctuation... (never thought I'd say that, one who hardly uses any herself), but also because of how you .. how to say it.. I'm missing certain words, as if you're trying REALLY hard to keep it short and simple, and thus forget that you CAN use prepositions (in, around, under, on) and conjunctions (and, or, but, yet) just as two examples, and still have the shortness and stylistic approach you're going for.
It might help with the flow here and there..
Otherwise, lovely idea and I am eager to see the result. Even if you don't change the rest of the poem, I'm curious as to what you'll do with the last stanza.
