here's my next Rig....the bow and  arrow which i believe was quite complicated for a beginner like me ...where the normal constraints had to be added and this rig introduced me to  joints which has been added to the bow, and clusters which is on the string and i got introduced to node editor.....well this isnt the node editor which iam used to in hypershade.....this node editor creates connections  between parent and child through connecting them by translate values rotate values etc....m still learning...comparing to all the rigs ive done this was challenging .....but learnt a lot doing it..
