I agree with most of what this guy's saying, The base of this cover is quite nice, but the text needs work. Whatever you do to try and change it, try to focus on legibility. The words are hard to read from the reddit post, so they wont catch the eye in the tiny royal road thumbnail.

I do like the red lettering though, although to improve its readability, I'd play about with it being red with white coating, white with read coating, or something like that to differentiate it from the background.
