Here's a blog post about perceiving the craft in one's own art. It ends with a chart relating "ability to see" (that's literacy) with "technical ability" (that's craft). It says, "The ability to see improves before technical skill, and we often have difficulty assessing honestly exactly how our work looks."
Some other charts based on this one. Not all of them limit technical skill by ability to see .
