Hi SarraB,
This is a fantastic poem. The tone is formal. It suits the poem and subject matter very well. The poem is about the peace and calm aspects of Nature, sunny days, quiet meadows and things like that. I love nature. I just wish we had more calm nature where I come from. We tend to get a lot of wind and wet weather. I loved this poem and read to the last word. The free verse works well in this poem, and you have handled it very well. There is a wonderful rhythm here. You have not used punctuation in this poem, but this does not interfere with the flow of the poem. You have used grammar consistently here. There is nothing to distract the reader from their reading pleasure. Great job.
