I rarely see any good poetry here, let alone well written happy ones.
I like this, overall. I don't tend to take to short poems, really, but yours are nice. I do think you could have chose some less distracting wording, like with 'wriggle'. . . that is, certain phonetic patterns in poems can throw people off if they're broken. Wriggle is a harsh sounding word that reminds me more of worms or bubbles than a story about sun. I'd stick to 's' sounding words or others that slip easily off of the tongue like that. But that's just me, because I read them to myself semi-aloud. It's in no way a criticism; it's all author preference. Just saying as a reader.
Otherwise, it's a very neat idea. I love how the sun triumphs over the cloud, and bursting forth from the hand to again lend light to everyone who needs it. I believe even that holding the sun could, in a way, symbolize how for a moment some people, especially writers, feel like they have all of the 'light' in the world in their hand. That is, inspiration and knowledge and rhythm. I feel like that when I write an amazing poem, then let it go for other people.
Well the metaphors really depend on the person. I like to think of it as alluding to grabbing onto your dreams, but that might not be so. I liked the imagry. It was intruiging. I mean a person laying in a field, grabbing sunshine, and struggling to hold it. It is beautiful. I liked how you described how the sunshine felt and its action, giving it animistic veiws. It brought it to life. Thank you for the read. Briannan
