This is good, maybe varying the tones/color values between shades by using the opacity (it's a slider tool at the bottom right of the applet) higher numbers are darker, lower are lighter, and then blending. This is a cute cow, I have one named Patty Cow. :)
Thanks DBA..I'll try that. How cool, that you have a cow. Where I live we only have lizards.:) I took a look at your gallery and the Texas Blue Bonnets picture is magnificent.
