Gorgeous artwork, fantastic perspective. I love how the dragon fades away so the figure stands out. That’s a great way to keep from cluttering the cover art. And again, my favorite, a limited color palette. The metallic font with the swirly ‘of’ fits nicely in the epic fantasy genre, and that same font as the author’s name. The thick atmosphere even gives a connotation of rampant disaster or war.
In agreement with your comments, 100%, The cover sells the book.
