This one is very interesting to me. Because the imagery is actually fantastic. And the wording is great. Okay. The first stanza shows me a bluebird (although simple the use of a certain colour makes it stand out more its great for this). I really like the clouds part to contrast the birds. Because I see the sky as light blue and usually birds are darker shades so the contrast there too makes you see them clearly. There is sooo much I can say about the last two stanzas. Anyways.

Warm rain and sunshine to me work well together because it reminds me of early spring when the rain is first starting to come in. And when they are mixed together they form a rainbow. So the lines connect well. Though the main character and story is about the bird, you paint a great scene. And I loved your title because dreams are supposed to be bright and happy just like the imagery you show. Anyways. This is such a beautiful poem overall. Well done!
