This is less successful than usual for you. If forced to single out an offender, it would be the pocket square. It too literally picks up the colors in your shirt and tie (the blues and oranges). If it didn't have the orange references in it and were predominantly a darker, navy blue, it would still marry to the tie and shirt, but less directly and obviously.
I think the shirt pattern is more appropriate for a casual sport shirt, but it's not killing the outfit.
