A common way to learn to draw is to place a paper on top of a comic book and trace the lines. The result is better than if you drew it all by yourself, and this positive feedback keeps you drawing new figures and scenes. Meanwhile you learn to draw.

This is how you can learn to draw with PainterTool. It can give you enough feedback to make your drawings fairly good. Whatever is different from the original photo can be corrected by comparing a photo of the drawing.

As you get better at drawing what you see, you will wait longer between comparing your drawing with PainterTool.
