I'd like to draw the whole Allosauroidea superfamily like I drew Troodontidae once.
I'm not that good at large theropods (yet), so I did some sketches to get the gist of their general look.
1. Acrocanthosaurus; 2.,5. Allosaurus; 3. Saurophaganax; 4. Sinraptor; 6. Carcharodontosaurus; 7. Giganotosaurus; 8. Mapusaurus; 9. Yangchuanosaurus; 10. Australovenator; 11. Tyrannotitan; 12. Neovenator.
Everything was done in ArtRage. I used a lot of references, mainly photos of skeletons.
