You tell me...you can see the difference in the pics, yes? Clean lines at the shoulder in many of the pics in this thread versus yours above (and versus those in the SS coats). It might be the pose. If it's clean in general, then ignore the pics and criticisms of it.
There was a post some time back in some thread of two men from the back where one had horrible wrinkles and the other had a really clean back. People jumped all over it until a tailor pointed out that, of course, you live in a coat, and it moves with you. A photo can capture even the best coat in an unflattering light (think of the most beautiful actress you know, and I'm sure you can find a horrible pic). So, it could be the angle or pose, but only you would be able to tell us.
