A broad selection of Superhero figures by a single artist who knows what he is doing. Very consistent in style and very usable. I, personally, produced a book a villains for my own game (Squadron UK - available through RPGNOW) using every illustration in this book. Though not at all artistic myself I was able to colour the illustrations and use them in a variety of ways with extremely pleasing results.
Best features: The consistent art style, quality of the artwork and the open-ended license.
Areas for improvement: In order to be unique and not generic, one or two of the figures have highly specific powers on show or are placed in unusual poses. I totally understand why this is done but it limits the uses to which the pictures can be put.
