It's a clear, readable font, and very pleasant to read. Very much suited to comics aimed at a younger audience.
But it's also a very wide font. If your comic is particularly verbose, you may get frustrated trying to fit large amounts of dialogue into a panel without covering too much art... especially if you use long words.
Even so, quite a bargain, considering that it comes with a lower-case version as well! With this pack, you'll have a font for both dialogue and narration.
