First model person

Hey ive been working on a model of a person based on a simple skeleton model i did for another project. Its my first attempt at a living thing and i have a few questions.

If i complete it as a full skin, how would i go about animating it? and if the parts need to be separate for animation, should i make the parts whole objects or does it not matter if they are open?

Also, as you can see there are still sharp angles on the feet, i have subsurf’d it but they remain, any tips on getting rid of them?


p.s. any feedback is more than welcome.
