In addition to all of the great advice so far, I would add one thing that helped me a great deal.
With regard to angle, pay attention to the *spine* of the blade as opposed to the edge. The edge is on your face and obscured, if you watch how far the spine is from your face, you can keep the angle better. Helped me anyway :)
Once you get a bit farther in, the angle will speak to you through the feel of the razor against your skin.
