I don't draw. People who can, even in that techie, digital way, are cool. In the same way that people who read music, or dance, or do other things I can't do are cool.
When I was younger, I used to write Sweet Valley High fanfic, and one of my favorite daydreams was imagining what the covers (of my fanfic stories) would look like. Totally missed out on the fact that my "daydream" was just the beginning. At some point, if it were the real world, an artist would take over, and that cover will be her creation, not necessarily mine.
Now I look at book covers that I like and wonder how involved the author was, or if, like me, they just went "Oooh, cute!"
