On my digital easel:
Today I am working on Chevy the Jack Russell and Buddy the Frenchie. Both projects need more color and more work. Check out the before and after details on each pup and you will see how important the eyes are.
Above you will see that I slightly tilted Chevy's head and also opened up his eyes a bit, adding some sparkle.
Check out the amount of white showing on the eyeball to our left above. I rounded out the eye's iris on our left so that the white portion was not quite so large and that eye seems to wander just a bit less. I also made the whites brighter to reduce the bloodshot appearance.
