This is the English translated edition for the original Japanese art book ストリートファイター4/スーパーストリートファイター4 オフィシャルコンプリートワークス which I reviewed earlier. So, this review isn't going to be too different.
This artbook collects the character sketches for the Street Fighter characters for the two games, not including the Arcade Edition. You'll see the character splash art as well as concept sketches of different costumes. Some characters have more coverage than others. Other materials included are the ending animation screenshots, background designs, some ads designs of characters selling food, storyboards and an interview with the producer.
This book is not as good as the few Street Fighter art books before, namely SF20: The Art of Street Fighter and the fan art book Street Fighter Tribute. If you don't want to get all the Street Fighter books, I would recommend SF20 and the refreshing Street Fighter Tribute, both at 320 pages.
Street Fighter character concept designs don't really vary too much. The characters are already designed, so design variations are going to be minor. I fear that might be the same for Street Fighter V.
As with Udon books, I would pay special attention to the binding. Mine seems alright at the moment. The book's a 176 page paperback.
3.5 out of 5 stars.
