I see you delema, 1BAT. Not sure it's the shoulder width, but the sleeve length that is the main issue. I say that because the sleeve will lay down, as the jacket is new and would need break-in time, but even if the shoulders were to lay down and comform to you, there will still be an even bigger length of sleeve to deal with. Somehow the measurements you gave didn't translate well to the Heron pattern.
The sleeve length and sleeve cuff circumference looks to be the issues here. I see that Heron made the sleeves flare out too much and swallows your hands. You should mention those two issues. As they may take your jacket, remove the sleeves and make the appropirate adjustments for you. Not sure if it's me, but the jacket could stand to be an inch or two longer in the body as well.
Not sure what happened, but if you discuss it with Miguel or Jorge, I'm sure they can replace it. I'm sorry to see your jacket doesn't fit like you had hoped.
