Love your daffodil poem, Echos.
I like the
sound of 'immortality' better, and I think if it fits what you feel better then you should go with it, as that's really the point of the poem after all. Having said that, the mention of the seasons seems to really fit with the feeling of the poem to me, too.
(and yeah, I know you asked Art, not me, but I thought I'd get involved anyway

)
