CRich, I quite like post #23. I like the choice of title font for a non-fiction work, and the font colours (the blue and the red) I think suit the notepad background very well (these seem reminiscent of the lines often printed on such paper). But...
You're losing your author name again - go back to the darker font, or make this one bolder/darker (it does not have to be the same font as the title).
Use your space a bit better: you have room on the right to expand your title and get a more centred/balanced appearance. Don't increase the font size, I think that just increasing the kerning (spacing between the letters) might be enough to give the balance this needs. And perhaps darken the title colour back to something like post #17.
You do understand that all this advice is "all in my opinion which does not sound quite so humble as it probably should" - don't you? I mean, it's not like I'm rolling in so much success that my advice should be written in
gold letters or anything.
