I was bored and got reminded of @oldshrewsburyian's post about how ugly the paperback cover of Malcolm Vale's Henry V: The Conscience of a King was and decided to attempt my own take of a rejacket.
I made, at first, three varieties based on the earliest version of The Portrait. I did feel a little bad about #2 being somewhat similar to the cover of Teresa Cole's biography of Henry (in crop, at least) but I also realised Cole's cover is also similar to the cover of Keith Dockray's biography of Henry so I ceased to care. Personally, I'm quite partial to #3 and I think I had something going on here with like the hands of the king or something...
The image on the hardback edition is from a manuscript edition of Henry being presented a book and, iirc, Vale references that image in the text of his book so I then tried to use it and discovered... circles.
Keeping with the circles theme, I turned to two other images of Henry. The first (#6) is the statue of Henry from the York Minster screen and inspired by G. L. Harriss's comments on it as a memorial of him as king. Finally, there's the manuscript of him receiving or giving Hoccleve's The Regiment of Princes, to which I added Henry's signature.
Personally, I think #4 or #5 is the best of the circles. I don't have any suggestions for a better subtitle, though.
