I think some variation of a long necked mama and a baby is in everyone’s mind. In part because that long neck is so fun to loop in your drawing and second because this is a large animal with it’s tiny offspring.
I blame my childhood plastic Brachiosaurus toy for why every Brachiosaurus I draw ends up blue. Here’s the culprit and yep this toy still lives at my house. This set of dinosaurs was the one thing I saved up my allowance for. I remember being so proud the day I could afford this big mama. Yes, currently this dino is super too.
