this is more so help for after your model has been completed and you want the character to move
after you finished your character, they look great, (i forget what keys were to merge the model, but i advise you to merge the model on completion) export it to an OBJ file and go onto Mixamo.com, this place will do the basics of the most difficult thing when it comes to 3D modeling...
that is rigging the model, its rather irritating cause if you dont do it right, you'll have really wonky animation or stretching. also dont worry about the colours or inverted mesh when loading it, you can fix that after you redownload the rigged model
after this you can go in and fix it up if needed to but the site does do a pretty good job (sadly i donno any cheat ways to rig faces XD (cries))
