Any tips for rig properly a biped human?

Hello folks,

I’m making a generic humanoid biped model that I’ll use as base for make the animations of different characters. I’m using rigify, so before generate the rig, I want to know if the base model looks good or it have any error. Also I would to know if I’m setting correctly the bones for make a correct articulation.

Here is some images, but anyway I’ll leave my blend file.
