Summary
"Villain Races" by Chris Metzen. 

A Darkspear jungle troll, an blood elf, and a naga.

Note: In Alliance & Horde Compendium, the original published source of the artwork, the picture does not have a title. It represented current Horde's Darkspear Trolls, the independent Blood Elves and Naga. Its unclear why Metzen entitled the picture "Villain Races" on Sons of the Storm. Although it fits for the Naga and Blood Elves at the time, it doesn't fit the Horde Darkspear as described in Alliance & Horde Compendium.
