Thanks for the feedback. I think the knees not quite straightening is fine, and can be chalked up to different folks having different gaits (my knees are usually still bent a little on contact). I agree that the arms feel stiff. I could probably find better arm poses, but I am wrestling with the rig a bit there, as some of the defaults seem a little weird to me (the forearm only has a single axis of rotation). Not wrong, necessarily, I just feel like I have to set more keys to get the right pose, and I may have not gone through enough effort.
I was going for stately (she is a princess after all), but not for “stiff.” But I think I may have found some of the problem. I thought I had shortened it to a 32 frame cycle, making 17 the exact middle, but in fact I made it 34, so the exact middle falls on a half-frame, and I think that is producing the limping sensation I am getting. I was trying to clean it up just now and Maya crashed. I will give it another go here in a bit, and see if that fixes things.
