Site B Expedition - Allosaurus and Ceratosaurus

Inspired by African documentaries that are sometimes shot at night, I decided to take the scene of a Lioness defending it's kill from a pack of Hyenas and transfer it to Jurassic Park. It's technically supposed to be in Site B (Isla Sorna), a few years after The Lost World film and another expedition was done to properly document the fauna and flora of the island. You can't tell but the carcass is tat of a bull Corythosaurus. Before the Allosaurus could eat it's fill, a group of Ceratosaurus attempt forced robbery.
I would have liked it if it came out a bit more realistic but I kinda screwed up with the pencil. Hopefully when I get a Wacom tablet I'll be able to fix it up!
