I'm sorry, but I disagree. karl, your tailor is correct in everything for the sleeves. Based on your picture alone, your right sleeve is shorter than your left. Your right shirt cuff falls higher than your left one does(if you compare it to the webbing in between your thumb and index finger) and your coat sleeve falls higher as well. It doesn't matter if left coat sleeve is longer than right one, if it doesn't give you the proper amount of linen showing on both arms. Some of the issues with your sleeve is the pitch and the fact that yyour tricep is stretching the fabric. The vent flares because your hind quarters(behind) is causing it to stick out(i.e. your butt is large and causes the vent to kick outwards). And no, it shouldn't kick out like that. I can't see the bowing of your left lapel b/c of the angle of your pics and cause you're posing. If you look at the fit pics here and guidelines, it says specifically to put arms at sides at all angles. The 2nd picture makes it too hard to tell. You gotta take that hand out of your trouser pocket - it may be what's causing the lapel to bow. I also see a hard edge at the same spot in the 1st pic though. Your button stance is too high. considering it barely covers your butt, and where it falls relative to your fingers, it'd say it's shorter, with a high button stance(bit ugly in my opinion but I always like buttoning points 1" below my natural waist).
My 2cents. There are much better trained eyes than mine, so hopefully they can chime in.
