Hyperbolops
this guy is not only the first time I drew a creature in an actual background, it's also fan art of a fictional ceratopsian made by Osmatar

Evolution of Metriacanthosaurus (eh, kinda)
the JP style metriacanthosaurus is pretty much stolen from JPLegacy artist T-PEKC
and the modern paleoart one is stolen from the game, Path of Titans

Evolution of Baryonyx (eh, kinda)
I drew baryonyx how it would be portrayed in 3 styles

1. Retro (like, 1800's-1970's)
2. Renaissance (ok, more like the JP style)
3. Modern paleoart
   If I can find the time to do it, I might redraw this one
