This is one of those rare photo-manipulations which truly feels like a coherent whole. Too often pieces feel out of place or the whole is surreal when that wasn't the artistic intent.
Your choice of inspiration is original and creative. I like the way you use the words to guide your image blending. The result is a beautiful picture, a place I would enjoy seeing in person.
As said, your technique is nearly flawless. I'm sure if I tried hard and long enough I'd find error, but I sure haven't yet! It makes the scene come alive.
The result is just plain stunning. Kudos!
