When getting creative, it’s important not to judge artwork during the actual process of making, and instead to focus on the action taking place. Evaluating artwork before it’s finished takes you from being present in the moment of creating, into a judgmental (often emotinally challenging) position of editor and critic. The added pressure of evaluating everything while in the creative mode could turn into second-guessing every mark made and force you to be cautious about getting anything ‘wrong’ at all. Artwork could be prematurely rejected before even finishing which could limit unexpected discoveries or the space to practice.
A constant judging-while-making-process doesn’t help you develop as an artist, encourage ‘bad’ art, messy mistakes or allow for the unexpected. The judgmental editor thinks it’s helping by critiquing the artwork but actually is limiting potential growth and improvement. Shut the editor down and focus on the making. It’s the way to improvement in the long run.
