tyrannosaurus head

just something else i did while working on the bambiraptor.
i've recently gained an interest in tyrannosaurus head, (who wouldn't, this creature had a pretty badass skull)
instead of designing my own head, i did a quick google search and found this
ØŽè‚̐X‚̃y[ƒp[ƒNƒ‰ƒtƒg@`ƒeƒBƒ‰ƒmƒTƒEƒ‹ƒX‚Ì“ªœ`

so i decided to create one, but being curious, i decided to represent the model as a fully fleshed out head instead of it being a skull. i took out some markers and color pencils and proceeded to color the head to be a fleshed out representation of tyrannosaurus.( although, i hate to say this, but the skull isn't completely accurate as i've went ahead and compared it to multiple tyrannosaur individuals and none turned out to fit.ex: the orbitals and antorbital fenestae are wayyy to big) but hey, thats being way too critical
so heres my build. i decided to take it a step further and make one side completely covered in tubercles while the other has a covering of proto- feathers. the left hand side still needs teeth.
heres the side covered in tubercles


and heres the side covered in feathers
