Impossible to tell with pic you gave, but that jacket looks to be one size too big full stop. Someone botched the measurements perhaps (if online service, I have to include the possibility that you botched your own measurements).
It is common when a chest measurement is made, they add 4" and then that is the jacket size. This works with most people but not all people.
A really cheap MTM operation would simply scale the shoulders according to a rule of thumb and then the sleeves and waist would be fitted according to your measurements.
It seems they did not work the jacket for your armholes and bicep size either, and the shoulders were no doubt generic according to some design rules they go by.
Is this a disaster? By Styleforum standards - yes. By general world standards, you will get by and the suit is serviceable. It depends whether you want to be in the 95% or the 5% that really go that extra yard.
If the latter, get your money back and explore RTW options if high class bespoke is beyond your means (monetarily or location).
