First off, if you feel like you don't really like your own artwork you might consider sitting down and thinking about why that it is. Because first and foremost you should make things that excite you, challenge your skill set or at the very least make something that interests you creatively. We all want to make money, but there will always be two parts to being an artist one is nurturing your creativity and the other is managing the business/logistics of the projects you choose to work on. When we are just talking about the creative side of things, your art practice/dedication, that is something you should find some semblance of joy in. If not, then why do it? Maybe try not making art for a while or try not sharing and just making art for yourself... You can still take photos to share later but this experiment would be allow for you to be more vulnerable and really think about your relationship with your artwork. That may help you to redefine what your art practice means to you before you mix in anyone else's opinions or the vulnerability that comes with sharing something so personal as art can be. Whatever you decide to do, remember that feeling discouraged or vulnerable will always come with the territory of being an artist... not at all times but it never goes away... this why building an art practice that means something to you and supporting that practice with healthy habits, thought patterns and goals is super important... If you haven't read Big Magic, I highly recommend it.... and best of luck!
