Here's my entry. I may drop in some value to separate out forms, but it's strictly a line-based character drawing this week.
Some cool pieces in here so far! A few that strike me, one way or another:
IVIATT - Nice drawing. Love those fingers.
Carnifex - I'd consider dampening or eliminating the glow on the gun. Right now it's the highest contrast area on the character and the eye snaps there. It's more important to see her working the panel.
Shogo - Make sure we know those are wires and not, say, branches. Maybe put some ports/connectors at the ends?
Kamikazuh - Looking good!
Saleem - Cool sword. Where's the hacker?
LukusMaximus - I like the cartoon proportions, though the hacker part isn't readily apparent. I'd give the white space around the figure a hard rather than a soft edge, and nudge the saturation and value of that red so it doesn't 'vibrate' against the green so much.
maria riaz - Where's his other leg?
nyje - More contrast! Everything blends into the same middle-dark value right now.
RichLyons - Killer design. Strong silhouette, practical gear. What's with the one yellow pocket?
Again, nice work guys!
