Okay! I have some drawings I did:

Jackie Estacado. He's the protagonist of both "The Darkness/2" and the comics of the same title. Awesome serpent-arms and guns with a lot of ammo.
I like his hair for some reason. It looks a little fluffy to me, game-wise.

My crappy attempt at Johnny Powell. He's a friend of Jackie, a graduate who become obsessed with dark relics and the occult and now he mutters to himself often. He knows a lot about the Relics you collect throughout each level.

And finally: Victor Valente
He's the main antagonist and he tries to steal the Darkness from Jackie using a rod called the "Siphon". There were few pictures to use as a reference (since I couldn't remember what exactly he looked like), but I managed to complete the picture.
Awesome,awesome game. Awesome art style.
I LOVE IT.
