This is the rig i been working on, thanks for the people who help me understand how to use some of the tools, and how to arrange things .

i almost over or at least i thinks so, before mirror the rig is something that i need to add, i don't know if there a animator in the forums that like a particular function on a rig, this is basically a rig that we can use at the studio, i try to mimic something similar to the auto rig of xsi, i was trying to find more info on IK spline.

but didn't understand very well how to set it up, using a curve and use curve to draw the bones, but later on how you control the curve and that when i got all confuse .

thanks for the review guys.
