So I was actually working on a picture and listened to music.
During the drawing process I was looking through my messages on dA and clicked on several ones and faved some of the artworks.
I went through galleries, saved some pictures on my desktop. Then I started drawing again.
When I suddenly clicked on my friend's gallery, I saw the progress she made.
So... then, I suddenly realized that not posting your own art does not improve yourself. Getting no critique does not improve yourself. You should show your art, even though it's complete nonsense or junk... People make mistakes, and through these mistakes you learn how to make it better
