Speed-painting Technique

This is a speed-panting of one of my old original Character. A cyborg jackal. Well, to be honest, this is one of my first speed-paint artworks. Turns out great, i presume. I did this in Photoshop CS3, with my Wacom Bamboo Fun in approx. 30 minutes.

I should do this more often, so i can paint more detail in less time.
