Thanks Omen!
Yeah it's a tough call with the coattails. The thing of it is, (and I can't tell you how many times I went through this whipping motion myself wearing a jacket with coattails) is that while the left leg is leading, he twists his back so that it faces the viewer. Since the coattails are connected to the jacket which is on his back, they naturally follow the twisting of his back and not his legs.
I'm working on the last couple coattail frames, I'll post the new results up soon. I think maybe having the coattails rest at a little more of angle might help too. I know it's right to have them follow his upper torso, but perhaps I could pull them back a little. And like Dracula 9 said, there still needs to be one more airborne frame before they rest.
Man I tell ya though, those coattails are gonna be the death of me!
Thanks for the input. Your whipping animations are looking good too!
