Just because you screwed up doesn’t mean its ruined. I had intended to make a black and white landscape with a dramatic splash of red, but after failing to make a proper cloud for a half hour I decided not to do a landscape after all. Remember to find the opportunity in your failures.
Also remember to learn from your mistakes. For me this time, I learned that I need to study up on my wet on wet technique, as this was the reason my clouds didn’t come together properly.
Keep on learning!
