I think having the designer's name is very much in line with the feel of this product, but that line break after "Fairy" is Not Good. Try the name in small type on one line, and the Fairy Market much larger on a single second line. As with the backdrop, this is another area where investing in some pro work could really pay off.
-- If it's not obvious by now, I think the game's design and theme are strong enough to compete in the big leagues. To abuse the metaphor, it just needs to suit up in the right uniform.
