I don’t know if I’d call mine cool, but I have made my own covers, even if just something temporary. Definitely seems to help.
Having always dabbled in art and knowing Photoshop etc definitely helps, and getting critique on covers as much as writing whether you are making yourself or not.
I see all these cool book covers and wonder if each writer designed their own, paid someone to create the book cover, or if Inkshares provided the book cover when writers hit a certain level of followers. I just took a Google image that seemed to fit well with my story (one that allowed reuse with modifications). How can I get a cool cover?
Before the age of reason and science, magic ruled the world. Now, it’s coming back and if most of humanity gets wiped out in the process....well, sometimes you have to break a few eggs.
