Could be a print orientation problem. Due to the nature of the printing process, there will be visible steps *somewhere",
and when the printing crew makes a bad choice of orientation (as they pack lots of models together in one print run), they
can end up on a more important part of your model.
Other possibilities to keep in mind if it is not one of your own designs - the picture in the designer's shop might show an
idealized software render and not a photograph, the model may be available in different material choices (polished vs
non-polished, or one of the high-detail resins), or the picture showed a post-processed (polished/primed/painted) model.
Can you post a photo, so that people can decide whether this is the normal aspect of WSF straight out of the printer or
really a misprint ?
