This is going to be a pretty short review because it's a pretty short story (a single chapter, a mere 16 pages) and not a lot could be said about it plot-wise without giving away a lot of story details that should be enjoyed while reading this. With that said, White Clouds is a very sentimental sort slice of life piece that, even in a genre becoming known for uniqueness, is quite unique.
Story: 10 (Outstanding)
The story is told through the perspective of an elderly dog watching over his equally elderly caretaker as his granddaughter comes to visit. Being a slice of life one-shot story, there isn't much to stay without ruining detail, but it's a very soft, warming sentimental story about life and moving on when it's time to go.
Art: 10 (Outstanding)
The art is actually very simple, but takes advantage of that simplistic style to achieve almost a surreal, softened image as if being peered through the foggy depths of memories gone-by. Lacking any color, the art instead uses the ample white space to create a surreal, almost heaven-like feel.
Character: 10 (Outstanding)
There's actually quite a bit of character development concentrated into 16 pages, and subtle actions are used to tell who these characters are while telling the story it has to offer.
Enjoyment: 10 (Outstanding)
Perhaps "enjoyment" is the wrong word to use here, since it ends with a rather sad note, but, to put it simply, it gets you every time. This is simply a piece that, rather than just reading about in a simple review, you should just make an effort to go find and read it for yourself.
Final score:
10: Outstanding
