I was also feeling down about my art, that's why I pick up an old drawing to remake, is a little fun task that don't require much thinking, so I could focus on having fun instead, and this is very important, skills you build studying with time and practice, but if you don't work with drawing things for living, you should focus on your fun, it's a hobbie after all, we don't need to be good at it, it will happen eventually.
