Great combination, love the shoes and jacket especially.
Your shoes are very nice.
Generally, I think this fit is suffering from having at least one too many elements to it. The tie and the square are too similar to each other. The grey jacket and blue trousers almost never works for anyone either. Would be easier on the eyes with say a plain white square (or no square though your budding Igent status would be revoked for that) and no cardigan for example.
