Colours used for this cats eye where: black, white, raw sienna, pathalo blue, yellow and vandyke brown. I used short flat shaders and blender brushes along with a comb brush , liners brush and a teeny tiny brush. In real time this eye took me approx one and a half hours to complete, but if I was doing an actual painting I would be painting both eyes at the same time to ensure that I get the same colours along with the same  tints, tones and shades in both eyes.
