Well, I've been trying to create a placeholder animation thing for human characters in Spriter, using the existing platformer essentials animations as a base and drawing the parts in Inkscape to create this featureless 'green man' with more realistic proportions compared to the platformer parts (once again using said parts as a base, while redrawing them to conform to the new proportions) - I'd use the default parts, but I'm not terribly fond of their proportions, even the smaller head isn't small enough. The end result ended up breaking the existing animations, so I might as well start from scratch. Oh, and the character I made has a proper animated neck, too. The idea was sorta to create a 'Tron' like character with minimal features.
And then I tried to animate the parts. The idle animation seemed to work reasonably well. The walk animation... Eh...
Ya see, this is why I'd much prefer having a proper animation person to work with, haha. Even the parts don't look terribly good!
Edit: Tried again, with some help from a guy over at NeoGAF who provided some advice for walk cycles, and I got this, which looks so much better:
