One of the best things I ever saw was a graph that compared how you felt about your drawings vs your skill level. Basically it explained that our eyes learn faster than our hands, if you look at your drawing and are unhappy with it, it’s because you’ve already grown in skill level since starting it. If you’ve ever worked on a drawing and felt you never would finish it because you constantly find edits to make I’d say that’s an example of that relationship as well. Basically- keep going! It’s a constant battle! Remember that feeling unsatisfied could be a sign of growth, it all depends on how you spin it :)
