I think your work is more heavily criticised than most because it is all commercial, and given your shooting environment, you have a lot of control.
For example, a street photographer has no control over lighting, movement/positioning of the subject, outside interference (someone walking into the shot unexpectedly etc). All they can do is previsualise the shot, wait for the right candid opportunity, and shoot quickly and unobtrusively.
On the other hand, your commercial style
modelling shots have none of the above challenges, but of course introduce challenges of their own. You have control over lighting and positioning your subject - probably the two most important aspects of photography

. You have time to pose your
model differently, use different lighting, different locations etc.
This is why your shots are more harshly judged than most. By its nature,
modelling gives you huge amounts of control over the final product, and hence it is judged more harshly (technically) than most other areas of photography.
Also remember, 95% of the shots posted here are not commercial. You are competing with established pro togs, whereas most are shooting only for their own pleasure, or occasional paid work. Professionals should be judged harsher than amateurs IMO - their skill should set them apart from us riff-raff
