hmmm, I also think the jacket looks a bit too short, even for a modern suit.
the waist may be too slim as your back vents are flairing
back of the arms (tricep area) there's lots of bunching
not sure about your posture, but a suit has two parts, and I can't really see the pants... pics of the pants fit please? (front and back since I can see some bunching around the back)
PS - there's a thread dedicated to this thing with tailors...
