I like simplistic designs and just a few colors (2-4 max). I want something that absolutely grabs your attention right away without looking tacky. I tend to be drawn toward books that have a white background and pops of color. When someone is scrolling through the Amazon store, I want this book title to make them stop and want to open it up!
I'd like for the cover to somehow convey a struggle--whether that's frustration, helplessness, stress, anger, etc., I'll leave that to the artist. Get creative and have fun!
Per Amazon's requirements:
The file must be JPEG or TIFF. I'm looking for a height/width ratio of 1.5:1. In other words, for every 1000 pixels wide, it must be 1,500 in height. To ensure the best quality, the height should be AT LEAST 2,500 pixels.
Amazon requires the images be less than 50MB and have minimal compression. The images should have a minimal resolution of 300 PPI.
