I had mixed reviews about this book, but I had to admit that the reason why I bought this book was because of his fantastic cover art. :)
First of all, there’re some really good references on the fantasy, science fiction and medieval world. For example, you can find knights, faeries, monsters, dragons and even aliens in the book. Plus, topics on evolving medieval weapons, differences between elves and faeries, special effects and even the turnaround section (which tells you how a person looks like when “turned around) are covered. There’s also a section telling you what’s a weak and dynamic drawing looks like, which helps if you’re interested in honing your manga-drawing craft. Another great section I would like to point out is the “Castle” section. The book also covers some different places within the castle, such as the dungeon and drawbridge, and I find this really helpful when drawing the inside of the castle.
Unfortunately, there are only one example for most creature, beast or place, which can be rather limiting if you’re trying to draw the same creature in a different way. However, I think this is where your imagination will come in. Also, I noticed that some of the artworks have a certain “American” style (instead of Japanese) to it, but many of the artworks are very nice and attractive.
For the serious mangaka-wannabe though, you are better off getting more “technical” & "Japanese style" books such as the “How to Draw Manga” Series, but overall, this book will make a great reference or resource book for people interested in fantasy and drawing cartoon/manga.
