It’s a good, well-rendered illustration. However, it’s not exactly dynamic; the static pose means that something else needs to bring the energy to this cover, and the only “something else” you have is the text, which is in a lifeless and boring font. But I think that if you replace the font, you can add enough dynamism to complement the illustration. Not that you need to use the wildest fonts imaginable, but you should look at period typefaces. How was the text usually presented on period posters and placards advertising fights? How was the magazine title rendered in the magazines in which REH’s boxing stories appeared? That’s where I would look for inspiration.
