Ok, a character description might be in order. I’ve seen some other people on here doing this so I might as well.
Lets say he’s some post apocalyptic biker dude cruising the vast wastelands of our native world (mad max style). The wastelands are beyond the grasp of the ancient and mysterious CgSociety - the ruling force on the planet, currently at war with 8 other worlds across the galaxy. When the ultimate weapon went off (whatever it was), it destroyed biker dude’s bike and ruined his day. It also stranded him in the middle of the desert without supplies. But thanks to the powerful magic introduced into the world by the weapon, the unexpected happened. In the middle of nowhere, he came upon a grotesque totem. Dehydrated and delirious, he thought he heard a voice urging him to come closer. As he approached, the totem seemed to melt and fall appart. Before he knew it, the thing was uppon him and all around him. Terrible skulls of molten metal seared his flesh and fused with his body. He awakened days later, a gigantic metal arm with the power to spew fire, was now part of him. Somehow or other he became instantly patriotic and decided to fight on behalf of the CgSociety. There you go.
Anyway, that thing on his back that creates a counterbalance to the arm is a canon. And his gun shoots blasts of fire.
I’ll post more sketches tonight. Stay tuned. If you have any design suggestions, don’t hesitate to let me know.
