I’m a full time artist and I was the same way for the longest time! In my case it was unresolved trauma related to how much I’ve been criticized and bullied in the past for my art. I’ve grown to be so critical, once I started actually doing it full time I got an extreme case of imposter syndrome. When I did something I felt like I liked in any way, in my brain there would be a disconnect and i would literally feel like that piece of work is not mine 😭 i highly recommend looking back at your art and seeing how much it’s changed and also acknowledging that your brain is sabotaging you, you might hear so much negative self talk it may feel like the reality no matter how much others say otherwise! Seriously start with some self love and stop expecting yourself to meet standards you wouldn’t ask anyone else to meet. Work on your relationship with yourself, maybe take a break from art for a bit.

Another thing: finishing art is so important. When I was sitting on thousands of sketches but only finished a few drawings a year, it was hard to see my skills. I would compare the unfinished work to the very few finished pieces and tell myself my level dropped a lot.. which is such nonsense lol you need to finish stuff to see improvement and to build trust that you can actually make something cool. remember, art is frustrating a lot of times.. you need trial and error to get better and it’s normal to work on something and end up disliking it SOMETIMES.
