Junkboy: Don't do it, it's a trap! Heh, always refreshing to see some Bladerunner Pixel/Oekaki art once in a while.
Helm: I'm not digging the calm look in the barbarian's face whatsoever. It's just not believable for me. Even the calmest psychopaths make some sort of weird face for a split second before they slice and dice someone. It's just instinct, no matter how dumb their facial expression may be. Maybe show some teeth, or a small smirk, if he is in fact showing some satisfaction, as the current material doesn't quite display it. Also, the description makes it hard for me to believe as well, seeing as how the front most barbarian also has a calm collective face. Was everyone this calm, during battles of days past, while beefy muscle men paraded half naked, threatening to chop your head off with huge swords?
I wouldn't believe so, even in a mythical sense. Just makes them more robotic, and less interesting.
But I'm no comic expert, so I'll leave it to your own devices to choose what is best. The inking looks great though...
