As a huge fan of Wayne Reynolds' artwork, I have been looking forward to this book since it was announced, but reading the reviews here I started to worry. I got my copy in the mail yesterday, and although I would still recommend this book, I also feel it could have been much better.
The selection of work is excellent- the only thing I really felt was missing was more of his interior work for D&D 3rd edition books, such as the Monster Manuals. Most of the art is reproduced clearly, including all of the landscape-format Eberron covers.
The problem is, as others have mentioned, the quality of many of the other images in the book. At least 25-30% of the pictures are visibly blurry, fuzzy, or pixelated. This is not a printing error- this is clearly a formatting error, so every book will have the same problem. Tragically, it affects some of the most iconic work in the book, including the Pathfinder and D&D 4th edition core rulebook covers, some of his standout Dungeon and Dragon magazine covers, and some of the Rise of the Runelords and all of the Curse of the Crimson Throne AP covers. With the landscape format AP covers already being printed so small, the fuzziness ruins the sharp and intricate detail Reynolds is known for.
I am still happy to have a collection of Wayne Reynolds' artwork, but I am very disappointed that some of my favorite paintings may as well not be in the book because the reproduction is so poor, and I remain baffled as to how Paizo could fail to get full-resolution copies of artwork from their own RPG.
