I started out with drawing simple sketches. I find using a reference photo much easier. So, I would prepare a reference photo, preferably one that is flatter. So for example, instead of a chicken from the front of the face, I would choose a picture of a picture taken from the side. So, the photo would appear flat and parallel to the face. Hope that makes sense.
This is the easiest way to draw for me. So I practiced every single day and I did 2-3 sketches a day. I still do around 1-3 sketches everyday working on my weaknesses. I have never been a patient person, so I couldn't stand taking a class. I like to watch a movie or listen to music while doing sketches. Sometimes, I get really busy, so I sketch at night. Either way, practice makes perfect!
