The house is full of dinosaurs when my 5-year old comes to visit, and the BBC “Walking with Dinosaurs” book is always open. A couple of sketches here taken from photos of the real live dinosaurs inside.
Peteinosaur was a small, early Pterosaur, about the size of a blackbird, I think. The fellow underneath is the boringly-obvious Bad Boy of the dinosaur world, T Rex.
Peteinosaur was drawn mostly with Pitt Pens, and a lot of fussy detail, the T Rex with a Pentel Pocket Brush, in broad, amorphous shadows and fluid lines. Nice contrast between the effects achievable with the two types of pen.
