The only error was the picture wasn't cropped properly at the bottom of the frame.
I fixed that. Removed your pen name as it didn't fit properly into the frame, it would distract from the faces of what I assumed are main characters. Now, even without the author's name, it looks more like a book cover. Kept the same font for the title, it's very sci-fi themed and I think it fits the picture.

P.S. I am not sure why I kept the "heart stopping" part, it's the template idea, but since your story happens to be tagged as the thiller it fits.
