I don't know if this aspect has been brought up. I'm just now getting on this thread and I kinda skimmed over it before responding.
But my point of view on how creation in Narnia responds to Aslan is that Aslan, in Narnia, is "the King of the whole wood" The same as Jesus is "Lord of all creation."
In the books though I have noticed that with the "it's always winter in Narnia," creation is responding to the power of evil, the same way that earth responds more to evil than they do the way of the Lord.
God said in the Bible that this would happen as Satan is the Prince of the Power of the air (i'm paraphrasing).
This seems to me that every evil source in Narnia leads Narnia away from Aslan "their savior" The same way satan leads Gods people away from their savior, Jesus.
This continues throughout the books, sometimes though not so subtly as in The Lion, The Witch and The Wardrobe, but it's still there.
In a way I feel that Lewis painted a picture using real aspects of life and made them into something even a child would understand.
That's just my opinion, sorry if it was in anyway confusing. I tend to ramble. lol
