Tyrannosaurus rex: Life on Our Planet Fanart

Some fanart of the 'Life on Our Planet' Tyrannosaurus. I think it was a neat design that has potential. Coloration and feathering couldve been refined (most definitely the quills) along with more muscle definition.
The head isnt as bad as I think some people make it out to be. It's still clearly a T. rex without it looking goofy. In my opinion, not bad of an interpretation.
