Steve,
I hope and imagine that your book will be a definitive work; a modern classic delivered without fluff. The proposed book cover does not communicate those high ideals to me.
The use and juxtaposition of typefaces, with weak alignment, hints at faddishness. The colors are vibrant but lack warmth. Rather than personifying smartness, the silhouettes at the bottom seem vague and ambiguous.
I can imagine a couple of directions you could go: a classic and modest look; a classic and ornate look; a bold and warm look; or a crisp and clean look. Although satisfactory, the proposed cover does not fall in any of these categories, to my mind.
I'd like to see your book achieve maximal sales. The world could use the help! And so could I. I plan to read your book too. As soon as possible.
