Drawings of the characters and scenery are perfectly rustic. The foliage is lush and the colors are rich. Although it does take a while to get to know the characters, because of the scant text, you learn about them fast enough I suppose. I missed buying all the original issues last year of the Fall series (I hear that they are hard to find how) so I recently bought the compiled book. The new comics of the Winter series have begun to be released, so you can buy them all separately, or wait for the larger collection book again that will surely be released next year.
For any parents who are tired of not being able to find decent storied comics for their children, this is a great one to introduce them to. While it does show that there are some bad mice (and hungry snakes) in the world, the main characters are full of honor and duty to each other and their kind, and are dedicated to being in service to save what's good in world.
