The more puzzles I do, the more I desire extreme levels of difficulty, which is why you'll find a lot more of my creations to have an overall bacground that's difficult to reconstuct by the piece. Especially the desert scenes where color varations are so slight, you can barely find a seam to work from. And now I've begun utilizing the rotation feature and that's just added so much more fun to puzzle making. I kind of wish Jigsaw Planet offered a 500 up to 1000 piece games.
