I don't always draw dinosaurs... But when I do, I draw MEGAPREDATORS. Despite Spinosaurus being the largest land predator discovered they may not have been the strongest, so I imagine their bodies were designed to make them appear even larger to intimidate other predators. Also to find mates I'm sure. That's my professional opinion, from professor Devon.
Actually I love dinosaurs. All of'em. Spinosaurus isn't even in my top 10 (I did it as a request), but she'll definitely do. It has inspired me to draw others.
Id have to agree, while Spino was huge in real life that Jurassic Park 3 battle would have ended with the Rex owning him. Rex was built far more robustly if you look at the bone density of both beasts.
all your style is... congrats!
Besides, I think the Tyrannosaurus is overrated, and Spinosaurus has a more interesting look to it.
Little Dinosaur: OH SH*T!!!!!!
