Okay again there is so much going on here and you can interpret this in so many ways! Dusk is the key word that is used here. The squirrels are just walking up from a long and harsh winter. So I loved the word tremble. They are not used to the cold yet and spring is just becoming in bloom. so all the animals have to get used to the warm again. Now where the word dusk comes in is I can imagine the squirrels being like a person in the morning, as in the animals have to shake off the cold just like people have to shake off the sleepiness. And both are just waking up. So I thought that was a great deeper thought of the poem. Anyways. I loved how you used the colour red as well it makes it more of a visual overall. Well done!
