Hey Man, looks good, one suggestion that I would give you is to add some extra loops round wheres your model will be deforming, it will really help when you come to skinning the model. Also if you want to anumate the high poly have a look into using the wrap deformer, this way you can rig and skin the low poly model (which is a lot easier when it comes to painting weights for the model) and then use this to drive the high poly model.

Also when you use the low poly model to animate your PC will move much faster (you basically hide the high poly, animate then at render time unhide the high poly then hide the low poly.) so it will make the animation a bit easier on your system.
