The bottom line up front: this is a superb product that is well worth the price paid! There is a nice mix of artwork that can easily be incorporated into a variety of products.
There are four character sketches and a number of items that obviously come from different cultural groups (including racial items such as elvish and dwarvish creations). The only thing missing are some critters and action scenes--but I am more likely to commission such material anyway.
Many of the pieces can be used as filler material--to fill that white space and add a bit of character to the page. But don't be deceived--the artwork is of sufficient quality that it can certainly stand on it's own as well. The challenge will be ensuring that the other artwork in the product meets the same high standards.
Easily one of the top three values I have purchased in the past year!
