Horses and Seahorse in double-ended black Sharpie on acrylic backgrounds over primed canvas miniatures. Detail in metallic gold Signo pigment ink. Horses are based on a sculpture displayed in the foyer of the Manning Building, Pitt Steet, near Central Station, Sydney CBD. Seahorse is from a photograph I took at Darling Harbour Aquarium.
Update: I saw a giant permanent marker in a discount store and had an idea to try sketching a zebra with minimal pencilled guidelines. I'm quite happy with the result. It's huge in comparison to the miniatures!
Zebra sketch inked with 7mm "extra broad" black permanent marker, with watercolour muzzle and background on A3 art paper.
