Those are daisies, not sunflowers, although it is very beautiful and I DID add this to my themes.
However, I believe you should definitely change the name of this theme. It's inaccurate, and there are just as many people out there who like Daisies, for example my niece, Daisy.

As a matter of fact, Daisy is coming out as a pretty common girls name for the kid to teenager group, so you might actually get more hits if you change the name.
