What happens when you're in the middle of a conversation with someone and they unintentionally mess up grammatically? The transfer of information falters, the communication breaks down. Focus transfers from message to medium when the tool of spoken language is misused.
The same thing happens when the tools of visual arts are misused. If you can see an errant artifact of the artist's chosen medium and tool employed, the illusion is broken and you see a painting instead of feeling the artist's intended expression.
In a pop cultural setting, think about when you see bad makeup.
So, it's all in the execution of the communication, in whatever form.
For me, internal consistency of brush strokes and paint density are key. If you look at my painting and think "that splotch looks out of place" or "he did something different with his brush there", and I didn't mean for you to think that, I've failed. Crap.
