Sprezz, your sleeves look fine to me. Personally I like my shirt cuffs to sit on top of my hands.
- pocket squares are nice and can add personality and balance when chosen well; don't be shy, investigate and experiment
- the lapels on your jacket are fashionably narrow, in poor proportion to both it and you, also the sleeves a touch short, and it's a tiny bit tight around the middle causing the skirts to stand up.
- your shirt collar is too small for you and looks uncomfortable, also a wider spread collar where the points hide more easily under the jacket, looks nice: I have the very same shirts by the way, and Sr Diaz pointed it out to me.
That's the criticism. However, in colours, textures and tones it's all very tasteful.
