Energise Yourself |
"Following the drawing and painting exercises makes me feel more secure, knowing that I do constructive things."
No need to erase any lines you think aren’t quite right, they can actually help you judge how to make adjustments if left in the drawing. Erase them as you are finishing the drawing later if you want.
Lots of famous artists leave all their lines in their drawings though, and regard them as part of the work.
