I think you could figure it out just by looking at the pictures you've shown us here, (especially the first one) and it shouldn't be too hard to figure out what needs to "stick out" when he walks. I think the leg should be easy; just a slightly sloped line down, then an angle an back towards the ancle to finish of with a foot. You might want to anle the other leg as well, like this: //\\ ........................................................................// || ......but properly.
Nobody here got the joke. Well, Sorta. Nobody here watches the Science channel called Sci? He has his own show called "Through the wormhole with Morgan Freeman". You should search it up.
I think you'll get pretty close for with the regular side view with an arm and a leg partially sticking out in a walking motion, if that sentence makes sense at all.
