The small monkeys are fighting against the emperor of Ape (King Warhammer Gorilla :D, you can see him running behind the Mecha, sorry for the author of King Warhammer, I just made the blur shadow of him, just to make the story ^^). They developed a machine call the Monkey Mecha, protecting them in the battle and become the best fighter on the Planet of Ape ^^.
Only the monkey is the external source from stupid-dancer (deviantart). The rest was done by drawing (you can see detail in the SBS, it took me 4 days to finish).
Also credits to Wacom for making such a nice tablet, I love it :x (3 years and 87 days ago)
