What Makes a Good Pattern?

I have been thinking a lot about my patterns lately. I want them to be the best they can possibly be, and work very hard to make them so. I worked for two years as a technical editor for Annie's Attic, where I learned the basics of pattern writing. But since I have been self-publishing, I have not followed the style I was taught exactly, but changed and added whatever I felt was needed to make the patterns better and easier to understand. Using testers has given me new insight into what crocheters like and want in a pattern. More stitch counts at the ends of the rows/rnds is one thing they suggested, and so  I have added more of them to my patterns.
I also add pictures whenever it is a little tricky to explain just exactly what I am trying to get across. This is something I learned from the old Elizabeth Hiddleson patterns, which can be a challenge to follow, but her clear pictures always help show just what she wants you to do. And I write notes of explanation whenever I feel they are needed.
Do you have any suggestions or ideas that might make my patterns better? I am always willing to try new things to make them easier to follow, and I love getting feedback. Thanks for any suggestions!
