I like the style of this type, it flows and the line is broken in areas, which reflects us as humans, no body is perfect. As a design I am not really keen on the image, I think the choice of colours are not very aesthetically pleasing, especially with the orange and the red of the hair.
This next image is of a font called Hand of Sean from dafont.com, this is a fantastic site for fonts, and there are a large variety to choose from. I quite like this font as the style is quite fun, which is what the book should represent, we want people to enjoy giving and receiving compliments, and not to see it as a chore.
This is another hand written style font called Journal from da font, visually it is a good font, however, as I re look at it, I am thinking it is a little too feminine. And may not be a good idea for something that is targetting females and males.
This font is called Christopher hand, this to me appears to be neither feminine or masculine, there are a few small swoopy lines which are often featured in more feminine fonts but there is also the inaccuracy of the letters like in masculine style writing. Most importantly, it is legible , and for all these reasons this could be a good choice of font.
This is King Cool KC, I like this font as it is clear and simple with consistent kerning. However due to the heights of the letters being the same, it brings about almost a child-like style, which I think I would like to avoid.
Due to the complexities of finding an appropriate hand style font, it could be effective to have a masculine one for the male compliments and a feminine one for the female compliments.
