I haven't goten to the "draw each frame" phase yet. I'm a really nooby animator so the way i do it is to draw the start frame, or use skullmageddon's start frame, then cut and transform pieces of the frame to animate. After the general idea is animated i'll go and make things less stiff like swaying hair and moving arms and shoulders etc. This is still a rough though some of the lines look clean.
This is a good way to go about doing something like her walk cycle because it allows you to quickly build a basis for your animation.
That being said, I have some thoughts regarding the latest attempt that I'd like to share. I can see what you're going for, but at the moment she feels a little floaty and here's why:
-She still doesn't retain her bent knees and posture throughout the cycle as much as she should. This would be a relatively fast shuffle and maintaining her bent knees is important, so her upper body would almost completely maintain the same height throughout the animation. Think of it more like she's using her back leg to push her body
forward rather than a leap upward. There should still be some up and down movement in the whole body, but do it in a subtle way without rotating her upper body from the waist up. If anything, her upper body would dip down as she bent her back knee before pushing forward.
-Like evilben said, there's a decently long portion in which both of her feet are off of the ground. In order for her to maintain her pose she not only needs to keep her knees bent and center of gravity low, but she also needs to keep her feet on the ground as much as possible. Rather than stepping forward with her back leg first, try having her push with her back leg
then step forward with her front leg. When moving forward all of her strength is coming from her back leg, not her front leg. There also shouldn't be any frames (maybe one frame at the most) where both feet are off the ground.
I'd like to hear what others have to say. Anyone agree or disagree with me? Also sorry for rambling, just trying to be thorough with my thoughts.
More importantly, if you haven't already done so try acting out the movement yourself. That's how I usually figure things out. Also try finding some good reference material to go off of. I don't know a lot about swordplay or stances, but try watching some fencing as a starting point.
