Do you ever pick up a book or ignore a book based on its cover?
If you're at a bookstore, library or just browsing the internet does the cover art attract your attention first or does the title/author?
I'd consider myself right brain (visual) dominant over left brained (verbal) so a well designed cover is pretty important to what I decide to look up and blurb-read.
With the influx of self-published authors lately, I wonder how much more attention their books would gain if they put more emphasis on a well designed cover over just a well written story.
An example would be
Toby Ball's - The Vaults novel.

The first cover looks very simple, standard ... and boring.
The second is eye-appealing and stands out and attracts my attention.
If I just saw that first cover, I'd probably just pass it over. The second stood out and I picked up a copy. Just started it and it's pretty good so far ...
