I think Poser renders will always have a large proportion of renders that are mediocre, the software is,  after all, aimed at the hobby portion of the 3D field.  Many users will use it to illistrate a book, if so they will often use the render to support the story so it may not be a masterpiece everytime. To them the story is the most important part. There are also those that are just learning and despite its limitations Poser is a hard program to learn.  I would not regard my renders to be of professional quality today but they are a vast improvement on what I was producing five years ago. 

They only person who can decide if a render is good enough quality is the creator, as they are the only people who knew what the intent was from the start.  Not that constructive help is not of value, I have had a few comments made on the renders I have uploaded that have been valid and helped me improve a render, but then they were comments from people with no axe to grind.

 

Poser is like life, if you try and arrange it to please others you will fail.  Arrange it to please youself and you have a much bigger chance of success.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
