I syng of a Mayden (??!)

I've hit on a brick wall and could do with someone else to prod me a bit (now I'm not at school I've got nobody to do this, which is partly one of the reasons I joined this forum).

Well. I've been thinking about setting the 'I syng of a Mayden' text for ages, and I had some ideas about one of the verses (this one), but I have virtually no idea how I should proceed. I don't want to stretch the pentatonic melody over all the verses (there are two more, very textually cohesive, of which this is the last), as I think this will quickly get boring, and it's probably better to leave this material for this moment. But the text itself hardly changes here (pretty much 'He came all so still to his Mother's [something], as dew in Aprille that falleth on the [something]'), and I want to keep this sense of simplicity somehow. Urgh, I dunno.

There's also a chorus: "I sing of a maiden that is makeless, King of alle Kings, to her son she ches. Mother and maiden was never none but she; well may such a lady God's mother be". I was thinking of splitting it in half and having the first bit at the beginning and the second bit at the end - Britten does this - but actually I wonder if the ending of the verse I've got here should be the ending of the whole piece. So I dunno, it feels too long and chunky to have before everything else, and definitely not between each verse.

Anyway, here's the score and midi of the verse I have set. It's actually been really useful to my decision-making process to type this out anyway - I deleted alot of stupid ideas lol - so you guys have been useful even before you've begun.

(Also, I'm not sure about how effective the final cadence is - I've heard it too many times to tell. And it's written with my Cathedral choir in mind, the tenor part's ok for me (and the other tenors, who are great) and the Eb in the bass is fine. Sop part is easy because the boys are crap :p).
