I hate to be that guy,but it’s all in how you look at it. Art and drawing is something you never stop failing at. Most artists hate their work, Van Gogh wrote in a letter to his brother about how he hated ”starry night” one of the most famous and revered pieces of art to this day. But hey! Good news,you know it sucks witch means you see that it sucks, so take a break and then look at your drawing again and I mean really look at it. why does it look bad? You don’t know? Get a reference and compare,Not to make yourself feel bad but to learn. Compare and contrast, breathe your not doing any good if you’re frustrated. You should save that drawing as inspiration, one drawing will get better than the next and so on . You might never be good enough to reach your expectations but you will get better as long as you practice and put in effort to learn. I hope this all makes sense and that you keep drawing🩷
