For comparison, I made three girls. I manually animated one of them (Yes, she is the one noticeably limping and moving like a log, how did you guess? 
). I textured the left one after the animation, and the right one before, wanted to check if there would be any problems after Mixamo.
great work still! Glad mixamo worked out, and your walk cycles will get better with each attempt.
From left to right: a male, a robot, a girl …
It’s so funny to see that animation is part of the way we interpret it.
@FedPete Oh, You a right! Didn’t notice it. Indeed it is very funny. We have two pretenders here ))))
@HobbyPirates Practice helps, this time it didn’t take me a day to do the walk cycle. And I already see what needs to be fixed. Examples of finished animation like this side by side are also very helpful.
