I believe the thought would be a nice, worn wood table or floor as the base for the image would look nice. Think old library table.

Unless you desire to juxtapose the old, worn look against a bright, shiny surface and background. For which some of the elements you have fit the magic theme of the book.

The cover is very nice, but I believe the wore-away spine end should be treated different. Got an old, wore-out book you could look at? I think one would be able to see some of the gathered signatures, and if so, should show some wore through and ragged and some still together.

Take care, Mike
