That's what I think too. Writing a proper prompt isn't an easy task, actually. You will never get something good looking quick. Even if you have an amazing idea, you will be rewriting the prompt again and again before getting anything representative. And there's a chance you will never make it anyway.

I agree with the posters above saying that concealing the fact that the image was made with the help of AI is unethical, but I think such images can be submitted in the Digital Art category if this fact is not concealed.

But, of course, it's up to the organizers to decide whether it's allowed or not.
