Done this back in 2017 for a paper describing tooth marks on a Centrosaurus skull belonging to a juvenile gorgosaurus by David W.E. Hone, Darren H. Tanke, and Caleb M. Brown
you can see the paper and my artwork here => https://peerj.com/articles/5748/
back then i did not develop my current style and theropoda anatomy knowledge, but i am still happy how it came out.
