I'm currently redrawing the animations and designs for the main Character of my Game 'Eternal Night: Project Dee'.

Anyway, shes not really nakid, I havent sprited her armour yet ... which is supposed to be an overlay in the final version. That way I can display different items on her, like boots, armour, helments, lingerie, weapons and shields.

I spotted two major flaws right away:
- Arms are too short
- The shoulders move too little

I really like the legs, though. Great frames

Her chest seems like it's up too high... if it dropped by just one or two pixels it might look more natural.  The leg animation is looking really good, but the arm comments above should definitely be looked at.

yeah, the first one was a flop because like blue said, it looked like her head was pinned in place.

Atleast in the new one, her body moves up and down a little more.

Errr... yes. Why do you ask? Okay, shes not wearing high heels all the time. Actually it depends on the armour shes wearing, but the orginal design had High Heels (can be seen here), and I'm to lazy to make a version where she isn't running on her toes :3.

The weightless feel is because she bobs in the wrong places. I recently made that mistake (unless you want it to look that way) myself. The body goes down during a walkcycle when the legs are the furthest away from each other. It reaches the highest point when they "overlap" in our 2d anims. I guess you thought about the jumpingeffect of pushing ones leg back, but when you "reach out" with the leg you are putting forward you are effectively moving downards.
