On the one hand, these miniatures give a friendly, jaunty feeling to the table, perfect when running a game for kids or a game that doesn't quite take itself seriously. They really convey a feeling of fun.
On the other, this style of miniature doesn't mesh that well with more realistic-looking paper adventurers. I hope they come out with more sets, especially sets of monsters and monster humanoids like orcs, so you can maintain a consistent look on the table.
