To become good at most things takes a lot of practice. This would include playing the piano, singing, dancing, and art. I draw four or five portraits per day. Quite often I am using a ball-point pen. I find that if I can draw well, my painting does well. Also I’ve found I do much better doing a portrait from a live person than a photograph. People have asked me to draw from a photo, but this method is rarely satisfying because the photos usually are flat looking, have no dimension to the face, and are just too hard to read. I recommend doing at least a half hour of drawing practice every day, and to draw from life.
