Suit looks perfect on you. Jacket sits well, sleeve length is just as good and the trousers more so even with the turn-ups. Personally, no need for the alterations mentioned above. That said, others may have different inputs
I'm urging myself to love this combo but there is something odd that I can't quite put my finger on. I don't know if it is the way you paired the shirt/tie and neutral PS (background seems somewhat busy). Apart from this, I love the fabric of the jacket
What a lovely pair of shoe this is. However, the pair will fair better benefiting from a shiny/glossy toe-cap. Albeit, done mostly for aesthetic purposes, subjectively, it improves the longevity of the leather and enhances the overall look of a well-put-together outfit.
