ebook fixed formatting for KDP

I would like a professional book cover for a paperback and e-novel. I've created something along the lines of what I want based on a stock Adobe image of an integrated circuit. My book is about a brilliant young scientist who creates the world's first general artificial intelligence, and who must then contend with his creation. My design concept is very simple (see attached) but I am open to any suggestions. I'm planning on my book being 5 X 8 inches. I'd create a short (less than 100 words) blurb for the back cover
