Alternative Diagram for Quadrupedal Launch

Please note that this is not an alternative launch hypothesis, but an alternative diagram for the previous launch diagram I posted.  The previous stage-by-stage diagram, whilst useful (I hope), doesn't give a good impression of the forward distance achieved by initial jump.  This image of overlaid skeletals is intended to complement the other sequence.

(The pterosaur is Nyctosaurus gracilis and the software used is Adobe Illustrator.)
