This particular branch of fantasy art is highly specialised and there’s more to it than can really be covered in a single volume. However, this introductory guide makes a very good job of introducing landscapes, buildings, characters and visions. There’s a good variety of subjects from the technical (machines and robots) to figures, animals and aliens. Techniques used include traditional pen & pencil as well as digital work, but it’s probably best that you have a basic grounding in your tools as this is more about working with them than learning to work with them. Geoff Taylor has worked for Disney Interactive Studios and has also done work for Microsoft and his experience and expertise really show.
This is an excellent production and to be recommended on that basis alone.
