CnC:
Pivot stick: Didn't have a problem with it, looked good.
Flash stick: Looked kinda weird, you shouldn't have so much smoothing on it. Couldn't find any details on it, it don't belong in a drawing, but more in an animation.
Fullbody sketch: It looked good for a sketch, because it's not supposed to have details.
Fullbody: I liked the cartoony style it had. good details, but no shading whatsoever.
Background: The background was just gray, nothing special.
Overall it's nice, but you do need to improve some. :3
I know how much you love shading, so this might hurt a bit: Not everything needs shading!
The flash stick was supposed to look like something pulled out of an animation.
I originally was going to put the backround so it would start out Pivoty and fadr into well done. Then ai thought, "Who am I kidding, I can't do that!"
I think I'm gonna shrink these down and put even more in the middle.
If you can draw a better guy with a mustache and clip-on tie who doesn't have a legitimate ride to work, I'll be sure to give you a very large cookie. :3
