I think poorsod's pictures may offer LTI the most help yet. This odd jacket is for Fall, and the shirt/tie/trousers need to embrace that. I think we also suffer from the angle and limited perspective of the photos LTI has provided -- we're looking at a horizontal slice across the torso and cannot step back enough. Certain features seem exaggerated.
IMO you are mixing too many patterns for a gunclub. I believe gunclubs are best with a simple or textured tie and blue (or other unpatterned) shirt.
