Just a few tips;
I think it's too fast, double the frames, or if you want him to run at that pace get a smaller up and down movement, it's way to much for that timing.
And you need some movement sideways as well. Delay the arms a frame or two to get it more organic.
Thanks for the advice. I just really wanted to show how quickly and powerfull Moho is when it comes to getting a concept out of your head and onto the screen I've done a lot of 3D animation and it takes forever to bring a character or a concept to life. so long in fact most times the creative energy is lost somewhere in the mechanics. This would have taken me 2 hours solid to do in 3D....instead it only took 10 minutes in Moho. Good on you LM
