First things first, the image is stamped onto IQ Smooth 160 g/m2 (availabe in Staples stores, not online) with Memento Tuxedo Black ink. And I'll be using the following promarkers; Sandstone, Cinnamon, Cocoa and Umber. (I have also used Vanilla for the mane and tail which is not pictured)
The first thing I do is to imagine where the lightest bits would be, this is the bit that most people fin the most difficult to imagine. The easiest way to do it is probably to do an image search of horses on the internet. This is one that I found - it might look awfully complicated - but if you almost close your eyes, so that you are looking through your eyelashes, it is easier to see where the light and dark areas are.
So I have started with the lightest areas and very roughly coloured these areas with Sandstone
Then I take a small section at a time and colour the remaining white bits with Cinnamon. Then blended using the Sandstone in small circular movements.
Next I take the Cocoa promarker and using small strokes, colour the darker areas. Then blend with Sandstone
The I repeat the above 2 steps (with the cinnamon, then cocoa) for each of the other small sections
I took the Umber promarker and added tiny shading to the darkest areas - the furthest away hind leg, and the back of the other three legs, and the shadow behind his jaw then blended with the Sandstone again.
Then I moved onto his mane and tail. I coloured the areas that I imagined would be hit by the light source with Vanilla.
Then used Sandstone to colour the rest of the mane and tail and blended with the Vanilla
I kept adding more layers of Sandstone and blending with Vanilla until i was happy with the effect
And this is the completed image made into a card
