Hm, the skeleton could be simplified a bit? There's especially some confusion in the ribcage. And the arms need to hang from the shoulder joint, not from the clavicula.
This isn't terrible. I agree with slow that the design of the skeleton is a bit off in places. But my main issue with this is that I really didn't get the sense that the skeleton was walking forward at all. The feet are flat and facing straight down the entire time. There's no sense of depth on the character which is necessary when moving in a 3d plane. Here is a good example from Tony White from his book " Animation from Pencils to Pixels: Classical Techniques for the Digital Animator " and DK also posted some good front walk cycles here on the forum as well.
Hope to see your progression on this! Good work so far, just needs some fine tuning.
Thanks Acochran_89 for guidnace. That Anime file is great WalkCycle.
And that Gif you mentioned, that itself a complete tutorial for creating front walk cycle. I will try to improve this. Thanks for comments.
