Penguin Student Design Awards: Final Cover Designs for Wonder

I've really enjoyed this project every step of the way and worked hard to develop an initial scruffy draft in to (hopefully) what looks like a polished final outcome.
There's just one last decision to make, as well as feedback yet to recieve for potential improvements.
I've been often lectured to look at contemporary fonts and work with type, which is what i've done here.
The question now is which font to use. These covers are getting 50/50 votes between being readable to the viewer, and playful and eye-catching to the younger audience.
The first is a bold, capital chalkboard style font that stands out the most from the cover, the capitals giving it great emphasis and power to shout WONDER.
The second is more playful and quirky, a font i found and adapted to replace the O from a heart to a star to suit the cover.
The 3rd, after an even divide in votes, makes use of both, allowing the title to remain stand-out while incorporating the playfulness in the author. The reasoning: the title MUST be one of the first things the viewer recognises, and while the author is still very important i feel this can be a bit more relaxed in aesthetic.
One woman in favour of the readable font was a worker in Waterstones, who knew her books and pointed out to me the books on a shelve at the other end of the store, saying that even from a distance the title can still be made out. That's why she voted the first. I mimicked this by place my cover printout further away and standing back, showing her point clearly - the first is the clearest.
Other opinions prefering the second comes from younger audiences, mums and people with young children (or work with children). They loved the fun and playful look of this font, saying it would appeal more to children.
Currently awaiting feedback from lecturers.

Feedback:

• The ladybug is too bright, being the only rendered object on the back cover. It sticks out like a sore thumb in the corner. Try drawing it in chalk in the same style as the rest of the book.
• Have a more chalky background. I've tried brightening the black but it made it less clear to the viewer. I'd like to dedicate a sheet of paper to chalk textured smears and finger marks.
• Try straightening the notes on the back.
• For the playful font: Make the star rounder to better act as an O. Have a smaller, rounder 'e'. Lengthen the 'p' in Palacio to be in uniform with the other capitals.
• For the readable font: Jiggle the letters into the grooves. One person likes how the playful font was positioned, even if it was the lesser of the two, so would like to see the better font composed in a similar way. They also suggested trying a star in this font and a squiggle like the 'd' in the playful one.
• The hearts in the playful fonts are too feminine.

At last! what should have been 5 minutes this morning turned into a day of emergancy rescue mission when the final Photoshop file was a corrupted write-off.

I can literally do no more to this until someone points out what bits are shit and need changing.

I've had so much feedback from lots of people, classmates, lecturers and Waterstone book-sellers put together.

Here i've adapted the text to merge both fonts i what try (one was playful, one was readable, this puts them both together to be capital, readable AND with a hint of quirkiness!).

The original ladybug too was too bold and bright, as i'd tried to make it look like a real bug crawling on to of the cover, but this was too distracting and didnt work at all. One suggestion was to blend it in with the chalk drawings, which is what i did here.

PLEASE if anyone has any complaints put them in the comments, Penguin's deadline for the Student Design Awards is coming up in March! :)
