But your name is Atrox. Shouldn’t you have done an Allosaurus Atrox?

Dude, one unproven peace of evidence does not prove that every theropod ever was feathered. Don't be one of those people m8

There's not much evidence for Carnosaurs having feathers. If it was a Coelurosaur, I'd be with you on that.

I think concavenator “quill knobs” were muscle attachments.

"Some paleontologists have expressed not being convinced by the conclusions of Cuesta, Ortega and Sanz. Mickey Mortimer pointed out the ulnar bumps appear to actually be on the anterolateral surface of the bone, rather than the posterolateral as Cuesta et al. claimed, and that crocodilians are a better reference than birds for reconstructing the muscles of Concavenator and other non-maniraptoran theropods. Mortimer maintained the ulnar bumps are most likely part of an intermuscular line.[7] [8] Andrea Cau compared the forearm of Concavenator to the articulated forearms of Allosaurus and Acrocanthosaurus and showed that this Concavenator specimen's forearm is dislocated and the ulnar bumps are on the anterior surface of the ulna and not the posterolateral surface. He pointed out this means that due to not being on the same part of the ulna, the ulnar bumps are not homologous to the quill knobs of paravians as claimed in both the original 2010 description of Concavenator and the 2015 results by Cuesta et al. Cau argued there are also other things that contradict the hypothesis that the ulnar bumps are quill knobs: the ulnar bumps of Concavenator are connected by a crest on the bone while paravian quill knobs are separate from each other, and the ulnar bumps of Concavenator are irregularly spaced while paravian quill knobs are uniformly spaced. Cau added that phylogenetics also make it unlikely an allosauroid like Concavenator would have quill knobs. He concluded that his interpretation was the ulnar bumps were part of the crest on the anterior side of the ulna perhaps for insertion of the musculature that connected the ulna and radius , pointing out that Balaur has a crest on the anterior side of its ulna which is homologous with that of Concavenator and has no relation with remiges "

1: Those quill knobs are not 100% verified as such.
2: I said not much evidence. A single genus we don't know much about is not "much" evidence.
3: Even if Concavenator's arm feathers were confirmed, that just means one carcharodontosaurid genus had arm feathers, not that all carnosaurs were covered in body feathers, so your complaint of this Allosaurus being "naked" wouldn't hold much water.

I'm not saying it should have a full coat. A few quills would be cool tjough
