Edmontosaurus with a fleshy rooster-like comb

Besides being a cartoonist I am also a paleoartist. I have been a paleoartist for decades. You can see some of my restorations at the Natural History Museum's in London site:
Natural History Museum London Picture Library
or at my old neglected tripod site:
Beri's Dinosaur World (BDW)
I am happy to note that although many of the life restorations of dinosaurs and other prehistoric animals are decades old (the oldest dating from 1983), they still can pass as reasonably accurate ones or even don't have any major flaws regardless of the recent advances in paleontology and numerous new discoveries.
To cut the long story short, recently a new wonderful and very surprising Edmontosaurus fossil with some soft body parts impressions has been discovered and described. According to this find, not only the various dinosaurs had the bony combs, crests, horns and sails, but they might have been decorated with the fleshy ornaments as well. The Edmontosaurus had a fleshy rooster's comb.
National Geographic Society site has the story. Julius Csotonyi has produced a nice life restoration for the paper and the magazine.

However, looking at the published paper, I have noticed that the fleshy comb might have been larger and of a bit different shape than Julius has painted it. Here is my interpretation:
