Yeah, I know that, still improving my animations. I am not yet advanced.
1. I watched Kiepocu Studios' walk cycle tutorial.
2. Sorry about that, just making them walk.
3. Not all. Only some.
4. I use framerate 3. Which makes the animation look extraordinary.
5. Probably, I used some cubic transitions.
Thanks, you liked my hard work, I admit my animation is not the best. But next time there will be improvements. :)
