I like the angle of your shoulder line (from neck to shoulder), sloped but not too much. Square gives a blocky appearance.
Traps peeking through on first 3 pics? (the 'lumps')
Someting else I was curious about...Am I correct in thinking that the amount of padding has nothing to do with the shoulder type?
E.g. you could do an unpadded roped shoulder or a heavily padded spalla camicia.
I don't mind the 'sloppy shoulder' look for casual jackets but for formal structured is...
