Concur with all the sentiment about wide lapels. To me, it's the chest that is out of proportion here, it's a tad skimpy. Chest is too trim from above the waist to the shoulder. This picture has a wider hip than chest that may or may not be so IRL. The skimpy chest and shoulder is not balanced with the lapel width or vice versa.
Sent a PM on how I would adjust this if he chooses to make a change.
