Pros: Fun to put to together. Interesting artwork. challenging
Cons: the biggest problem with this puzzle is the shape of some of the pieces I have never seen pieces in other puzzles with similar shapes. in some ways it makes the puzzle harder than it needs to be. in some ways the odd shapes makes the puzzle easier depending on the area you are working on. This puzzle is a little bit harder than most puzzles I've put together. if you are looking for a more challenging puzzle this one is one with its odd shaped pieces.
