Commission from a photograph.
Drawing from a photograph is not something that comes easily to me. For me, drawing is about the immediate experience, and a photograph removes that entirely. So, how do you tackle the portrait from a photograph commission? For starters, resist the tracing option. That removes even more life from your work. The key is in the attitude of the artist. Prop it up, and think that that photo in front of you is a real person, who someone else loves very much.
