The jacket is too tight in the waist, do you see it pulling like crazy and the lapels buckling? Also, the shoulder lines look like roller-coasters. That may be because your arms are up, not sure. There is a loose thread near your left sleeve buttons. I suspect these sleeves are too long and do not show any shirt cuff when standing normally.
@Anon: it’s really hard to tell about the shoulders and the pulling around the button because of the position of the arms. So until we see him wearing this jacket in more natural, relaxed position, this kind of criticism isn’t gonna be constructive.
Long sleeves and skinny tie with wide lapels though – yeah, that needs change.
