Added spots and some mane today and generally tidied everything up a bit. I photographed the picture in decent light this afternoon so this is pretty true - just waiting to hear whether the spots are prominent enough, I'm erring on the side of caution and just hope Zinc's mum doesn't know the precise location and size of each spot (LOL).
Once I get approval I'll just add the whiskers to Zinc's muzzle and call the portrait finished. I've enjoyed Zinc ... I do love horses. Next 3 subjects are all dogs - but equally beautiful of course :-)
