Head Reconstruction- Lipless Tyrannosaurus rex

This is not a reconstruction, but rather it is a fun test I wanted to do with experimenting with liplessness. Obviously, I don't support the science of lipless Tyrannosaurs, and theropods in general, but this is more of a "what if" question than anything, as well as somewhat of a design concept? Not sure.
The piece was rushed too, so please ignore the different stylization when it comes to the art.
