For an art book there’s a lot of text (that would be where the “Origins” in the name comes from), which kind of steals the show. Yes, the art is absolutely gorgeous, but the behind-the-scenes looks at the show are a must for any fan of the series.
It can be hard to tell if some concepts are still where the show is headed. Most importantly: is that what the Cluster would actually look like were it to take its form? (Obviously it would be much larger, but Peridot teased us about its appearance and we just have to know.)
Hurrah for good merchandise though! If you haven’t bought the art book by now, you should definitely get yourself a copy.
