I do like black and white looks, including Ronda Rousey's new book cover for My Fight/Your Fight. Feel free to get bold with color if you'd like.
You can go to http://www.roydeanacademy.com and see my current branding style. I aim for a very clean, elegant and classic look. I'm looking for my brand to be the Mercedes Benz of Brazilian Jiu Jitsu. High end. Intelligent.
You get the idea.
You can check the styling of my DVD/Download covers here:
I want this to be recognizable as a book, rather than a DVD. That probably means title priority over the image(s) that you choose (if any). I'll attach a few which could be used. Feel free to follow your vision.
Finally, I'm working on the sequel which will be called "Becoming The Black Belt." I'll probably go with the same designer for the next one as well to insure uniformity.
