Quote from DarkCloudWell here my first try at walking
C&C please since noone did before...
First of all, when people walk, they generally dont life their feet that high, it generally hovers in mid air just above the ground, and moves forward.And the arms usually pass in mid stride (when the legs cross), both of them that is. It also looks like your guy gains an arm in your animation. There should also be some easing. For example: (without the resizeing.)

Quote from DarkCloudMade a hammer smash thing
C&C please
You got nice force on this one, but the movements were off and it was chopyy. I also saw some wobblyness, but that will go with practice.
SO basically. Keep on Practicing!
