Orpingtons. Disqualifications? Puffiness aspect?

Anyone ever showed Orps?
Now, while I'm not ever thinking about showing my birds, I'm interested to know what would be the disqualifications, and what to look for when I try and get some more.
Here is one of my roosters. How tubby, on a scale of 1-10 is he? I feel like he doesn't quite reach the proper Orpington standard.

Idk, there's something about having puffy birds walking around your yard.
