Discovered by Professor Otto Liedenbrock, his cousin Axel, and their Icelandic guide Hans, the Liedenbrock Sea carries them 600 leagues beneath the surface of the Earth - from below Iceland to under the central Mediterranean. Filled with all manner of vegetation and prehistoric creatures, this is an imaginary world within our own world.
The trickiest thing in this image was the dinosaur, which I sketched out on graph paper and built from blobs, coding the coordinates by hand. It is based on ornithomimid dinosaurs of the Cretaceous period, but has teeth, unlike some of the better known species of this type such as Ornithomimus, Struthiomimus, and Dromiceiomimus. Well, the teeth make it more like a Deinonychus, Troodon or even Velociraptor, but the body shape is more slender and the neck longer than in these raptors.
The pterosaurs are identifiably Pteranadon, thanks to the
obvious head crest. I'm particularly proud of the aurorae in this image,
and the mushrooms look quite good too, I think.
