Seriously though, whenever you feel bad about your art the best thing to do is STOP EVERYTHING YOU’RE DOING. Drop everything. Seriously. Get out of that negative way of thinking. Take a break, go do something fun just maybe, go play with your pet, call up that one friend of yours, grab taco bell, watch that series you’ve been putting off?? Watch some movies…. get some ice cream??? Ok.
Then when you’re not being all negative nancy about your art, you’re gonna want to to go through some of your recent works. Find stuff you like, stuff you don’t like. Compare the two. Make a list of things you like and want to keep in your art. Then make a separate list of things you absolutely hate and want to change. Basically you’re giving yourself an analysis. If you can, ask for feedback on these lists of yours as well to get another point of view. Once you’ve done that, you can start working on what you’d like to change about your style! Set some goals! It could be that you need some improvement in coloring or maybe anatomy, or maybe you want to draw more of something you just aren’t good at! (My goal in college was to get better at humans since I drew mostly animals..and well look at me now). Most of these things just require a good amount of practice and seeking out artists you like who have the qualities you want to add to your own works. It’s also helpful to keep art blogs of these people bookmarked so they can be a source of inspiration to you!
You’re basically never gonna feel good about your art unless you do something about it. You’re not gonna magically feel better about it overnight either after doing this for a short while. It’s something you have to keep at and give some TLC to constantly. You need to be more passionate instead of being more negative. It’s ok to feel a little down about your art, that’s normal and we all have days like this! But like, you can’t stay that way forever. Things aren’t gonna get better unless you want them to.
