This font is clearly Serif because it shows the dips and tails. I like this one because it's not too complicated, but at the same time it is not too plain.
This font is Script because it is similar to someones handwriting. I like this one because although it does have the Script look, it also adds hearts for decoration.
This blocky font is Decorative. Each letter contrasts from another. While some letters have white backgrounds and black letters, the others are the exact oppisite.
