Now I can show the entire process, step-by-step, for how the Spinosaurus painting came to be, from preliminary sketch to the finished artwork. A scan of the painting is at the end.
Hope you enjoy the pictures!
I first began with an initial sketch to set down the composition and shape of the dinosaur, as well as the eel he's catching.
Next I added in some details and scale patterns that I thought would look neat. Note the little spines on his underbelly, somewhat like the spines on the throat of a bearded dragon.
I copied the sketch on a sheet of tracing paper, then used that and a piece of graphite paper to transfer the shape onto an 8x10 inch masonite board.
Here is where the trees and background begin to take shape, the water is filled in, and the two animals are given a contrasting color scheme for visual interest.
Many details and highlights are added in, from the tree bark to the Spinosaur's eye.
The finished work, with water highlights on the wet parts of the Spinosaur's hide, and dark stripes and spots for more of a natural pattern than just being entirely red.
The final scan of the image.
