I'm trying to teach myself how to draw movement in the typical shounen fashion to help out a friend with his comic drawing troubles. I kinda fail at it so I want you guys to give me a little help with improvements. By the way the thing I'm having the most problems with is the physics of getting hit, if anyone'd like to explain this to me then I'd love them forever, unless they do something to irrevocably alienate me.
Your line work with movement actually looks pretty good, but it might help if you use less lines on the left (in this case) side of his leg. Those lines are supposed to give the illusion of a motion blur, which only goes in one direction. I can't tell exactly what's going on though. Is the guy on the left getting punched in the face, or is he blocking with his hand? If he's getting punched in the face, there isn't much wrong with it, other than the amount of space between the fist and his face (they would be making contact here). If it's early on in the punch, the position of the face is fine, but a little further in, his face would be turned so you see only see the profile. On a side note, if he's squinting, chances are he'd be closing the other eye, since that's the side of his face that's getting punched. If he's blocking, you might want to angle his arm inward more. In this situation, the arm gives in a little bit even though he's blocking, since there is still a force being exerted on his arm (you asked for physics XD). So unless he's got a REALLY strong arm, where the punch does not cause his arm to move a noticeable amount, then lean it in toward him more.
Well. You're not bad yourself. I don't understand why her legs are also moving while she is punching the guy. Is she kicking? If so, the lines shuold curve to his face also and make a drawing of her feet contacting that shockwave point. Nice job though. I like it as it already is. ^^ *purrs*
Definitely much better. I love those lines that wrap around the left leg, it gives a good sense of power. The biggest weakness is the guy getting punched. If realism is what you're going for, then you need to make his neck shorter and his head moved in some way. From where he's being hit, his head should probably either be turned to the side, or tilted down toward his shoulder. I also must commend you on the proportions of the body. They might be a LITTLE tall, when you consider the size of their heads, but you can use that as a style. I'd like to see what this looks like if you refine your work more. You should still keep most of the quick strokes, since that creates personality and the look of motion, but be a little less sketchy.
The left guy's arms are gone! XD They need to be there. I need to see what position they are at because they too tell us watchers the motion that just happened a few min ago. THe leg movements are much more better right now and better used as the right person took a step to pound lefty. Nice job! ^^
His arms are actually there, but they are really rough sketches and there are no hands attached to them.
Oh. XP Sorry. XD I can't see much from rough sketches. It would be nice if I could see hands clearly with the arms also.
