Drawing a humanoid character can be intimidating, but it doesn’t have to be. If you’re starting out, using base materials to trace over is okay because that helps you develop the muscle memory to draw things properly. Every journey of a 1000 miles starts with a single step.
Tracing over drawings or tutorials is a technique called Rotoscoping. It is especially important for animation, as you can start to use different drawings at different times to create a sense of motion.
The best thing to do is use a tablet or touchscreen computer, save the pictures on the website and start tracing over it in programs like Procreate or Photoshop. I use Procreate for the iPad for this tutorial.
