Yes, improvement works. This is the second assignment where I submitted images, at the first one, that with the dreamstime logo
I worked hard, I learned, I made tutorials, I was reading documentation, and at this assignment I had one illustration selected.
I was very happy, and now seeing is 21 from 38, for me is a very good place.
Keep working, and keep improving and you will succeed.
Thanks at those who voted me.
