I am not sure, if I know the old version you are talking about. The walking animation I got from Diego is kind of hunched, but it is not nearly on all four, so reverting to this pose would look silly. Here is a comparison between the starting position in the walking cycle (left) and my running cycle (right).
Maybe I should really just create a running animation without including the arms...
But just remembered, that my "searching" position is also more crouched than the walking cylce:
Do you think, this might also pose a problem?
