The head looks very good. Back when I tried to model, I could never get a decent looking head.
I'd recommend looking into sorting out your smoothing groups - I think that's why it looks so angular around the hands.
Also, the model may be a little too low poly. You need enough polies to prevent distortion when you animate the model. I assume you're gonna want to animate the model, unless you're making a scarecrow game.
