The author says:
The main character is a wolf who lived in captivity and was recently abandoned in the tundra, where he must learn to survive. Throughout the story, he meets various wild animals with whom he forms bonds. The plot has many moments of drama and introspection. The novel is in Spanish, but I would also like an opinion on the cover design.
Nathan says:
The biggest problem is that gray is a dull color. It doesn’t draw attention to the book. And because most potential readers will first encounter the book online with other reading options on either side, it will get passed over. Adjust the contrast so that lights and darks stand out better.
The photograph has some distracting details to it, most especially the dark mark in the snow over to the left. I would remove all the details of the snow close to the edges of the cover, so that attention will be drawn to the footprints.
Finally, the typeface doesn’t add anything. I would experiment specifically with some handwritten fonts, and see how they add character to the cover.
