...and tips....it was a long time since doing this one. I can remember I made as much of the book cover picture off the cake on a dusted cake board so I could work on it a lot better.
I worked from the background of the design, and added layers of detail as I worked towards the foreground. The book cake itself took about 5 hours to cover, but the design took me about 3 days as I needed to let bits dry. I put the whole design on last, and did bit's'n'bobs after. Hope that helps ^^
