Daniel Krall posted some typically amazing-looking design work for Doom Cannon at his Tumblr, and I've been racking my brain ever since trying to remember if it has ever been officially announced anywhere. We can tell it's for Offset Comics, where he's also working on Doublecross, because Ivan Brandon posted this in February, but it has yet to appear at their (already very juicy) list of ongoing projects.
Krall states that "it’s kind of a riff on teen robot pilot cartoons (Voltron, Evangelion, etc). Like most illustration types, I think character design is one of the best parts of the job."
Very cool-looking work, and it kinda reminds me of how much I miss Sym-Bionic Titan, too.
