When I saw this in your gallery I was thinking to myself 'please let this be an illustration for a book, please let this be an illustration for a book' and then when I clicked on it and found out it was not I was like 'Aggghh!'
But seriously, I've always wanted to read a fantasy book about some sort of immense treetop civilization.
That's true, and when I was reading 'Fellowship' they did go into a lot more detail than in the movie, but personally I'd like a book that just stuck to that setting and stayed there. Maybe one of prequels by Tolkien's son has something like that, but I haven't gotten around to looking yet. But if you ever get commissioned by some fantasy writer who is, let me know because I'd love to support that.
