It's been a while since I last painted any dinosaurs, and so this is my painting of a pair of Allosaurs basking in the sunset and looking of into the distance, probably at some commotion created by a herd of Diplodocus nearby. It's still a work in progress but I think I got off to a good start. However, I somewhat "cheated" because the colors and lighting of the evening setting is based on an image that I saw from the net.
The sketch below was the initial idea.
Here's the image that I referred to; my lighting and colors are heavily influenced by it. I got that image from the net, so it is copyrighted to whoever owns it.
