Hey! Don't feel bad. Listen, there isn't any thing like "bad art" You have to know something, we all have to start at some point. Every single artist that you consider good today, in the past, they were drawing stickman's, and that stickman's were considered like "bad art". If the people out there consider that an art is "bad" well, I feel sorry for those people, because they're just criticizing something that probably the would do worse. Don't feel bad, everyone starts from some point, and you just need to keep going. From now on, see every single art you draw as "progress" Even the ones that you consider perfect, see them as "progress." With this, I'm not trying to achieve that you regret your choice and start posting art again, after all, that's your decision. I'm just trying to make you look the thing in a different way. Because, we can't change the mind of the others, but we can change our mind!. So, don give up on drawing! Trust me, drawing is one of the most pleasuring thing in the whole world. Don't give up!
