Gorn, post production

I did some post production work on the illustration for Gorn. Compare it with yesterday's to see the difference a little bit of layer work can do in Gimp. I added two layers, the first was a copy of the image blurred then set to "lighten only" to give a shimmering look to the whole thing.

The next layer was also a copy of the original, but I scribbled in some dark greens on the shadow faces and light yellows on the highlight faces. Then, I set that layer to "overlay" and tweaked the transparency a bit. All this gave the image that more dramatic contrasty look.
