Let's start this post with an admission - I am currently drawing on paper instead of the sketchbook for the time being.
After putting off doing these dinosaurs (wish I hadn't worried about them so much now) I really enjoyed them and once I started I just kept going.
So the three dinosaurs I decided on are - stegosaurus - triceratops - apatosaurus
So there you have it - my three dinosaurs. Now I just have to wait and see what Emma comes up with next...
