here's something i learned already

rigging is really important.

you may have really great looking concept art , but if the rig is stiff, or doesn't work in some other way, you cant realize that concept in your imagination. sorry, in your animation. The animation will never see it. Rigging is really important, and when doing facial blendshapes it's an art. Rigging really is describing the limits of what a model can do. Putting limits on the animators.

didn't mean to vent. anyways, like i said, rigging is really important, get someone good to do it, or if you're a control freak or perfectioninst lead, learn to do it yourself.
