don’t beat yourself up so much if you make mistakes in your art. you are still growing and you’re not going to get something right on the first try. it’s okay to screw up with a picture or notice faults in it. a baby bird doesn’t soar the first time it flies. there was a time when you weren’t as good as you were now, do you remember? there is no need to get frustrated about it. one day you will look back and think “wow, i was so silly to get so mad at myself. i improved so much” 

you have to make those mistakes to learn from them. draw a bad foot. draw a wonky hand. draw tons of them. one day you’ll notice they aren’t as wonky as they were before. don’t give up on yourself because you can’t get something correct - you don’t think picasso ever drew a wonky hand? 

practice. take care of yourself. art is fun - don’t be afraid to have fun with it…! ;^)
