I went back and worked on my dino pic a bit more. I experimented with the different airbrushes to get a freckly, scaly look.
Some of the brushes work better than others. As you can see by the patterns on his shoulder there on the right, it just looks a little too ‘spraypaint’. More like static and less like the skin of an animal.
I keep looking for an easy way to paint scales without painting every single scale. I have an idea that if I just put in a shadow and a highlight, I can fool the eye into thinking it sees scales. I kind of accomplished this on the little spikes on his head, in the red part and the blue part. If you look at those bumps, they’re mostly just some shadows and a highlight.
