you talking about the 3-frames-main-run 8D? well let's say that's not a bug it's nice (stupid) feature of the engine I'm working with^^ [You only have 3 frame per side]
Like you i also thoght of more frames (more frames al ALWAYS better :P [ You will see that on later animations... probatly xD)
But thx a lot!
You should really add some more frames to that one, because right now you have just two, and it looks bad.
It's nice, but why does his ass jerk out for a moment before he starts running again? And I find it amusing that when he stops, he looks to be sitting. More like a visual artifact.
