Coat lapels are cut to wide. The waistcoat is poor, the 'V' is set to low for that style of waistcoat. IMO Not fussed about the bottom button being left buttoned. The notion that the bottom button should be left unbuttoned strikes me as the wrong side of pedantic. Overall, the suit looks like modified RTW and not a bespoke garment. Material seems like a flannel chalkstripe, which looks fine.
