Just something I made to highlight the differences. It's hard to believe how much my dinosaur drawings have changed in one year. As you can see, the new version is less shaggy, with more subdued colours, and more skin detail. Not as majestic as the original perhaps, but I think the overall effect is more realistic and bird-like.
I think T. rex would look almost exactly like yours, the only difference being that males are the bald ones, complete with a flashy crest, and very dark plumage to emphasize that head. But I do think that the fully feathered females would have that color scheme...
I went with the interpretation than Tyrannosaurs had keratinous growths on their heads, instead of crests like chickens. Some tyrannosaurids like Gorgosaurus had actual horns.
