Cold. It was a cold aura around it... around pretty much nothing. It wasn't there... just the aura... of disappointment. To let down implied a specific dose of cold. But - at least - in another's case, it was unexpected. I'm glad I received so much good feedback for this simple work. The original horse sketch was not great in detail but I could obtain some nice variations by changing colors and constrast or light and other like those. As in many cases before, when I experimented color changes with a computer program, I got many more interesting hues and combinations. I thought this cold atmosphere suited this the vbest (as there were pictures that went better with blood-red, deep-blue, poison-green, etc).
