I'm not liking this one much C'horn. Shirt, tie and square don't gel imo.. The rest depends on whether this is a suit. If not a suit, my objection would be the cutaway buisness-y shirt collar and the tucked pocket flaps in a casual fit. If a suit, flaps and shirt are fine, but imo still a prob with the 3 FU elements (shirt, tie and square) together.
Jacket, not a suit. I hate flaps, both in appearance and function, congruency be damned. The shirt by itself is incongruent as it is a full spread in a very rough linen (the jacket is also linen, despite peak lapels). But I think I've become oblivious to shirt collar incongruity as I where spreads with everything (including untucked without a jacket).
Oddly enough, this didn't really feel much like an FU look to me.
