Very difficult for a 500 piece puzzle. Colors are very uniform and drab. The box image looks photo realistic, but the actual puzzle image is grainy, blurry, and dark. All of this combined makes it almost look like a bad cartoon or hastily colored line art. Had the colors been brighter, details like stitching in the back plate or chips in the helmet would have been easier to line up and complete. Will only return to if a very challenging puzzle is wanted.
