I have always loved monster manuals, I still do, so when this PDF came out i knew it was going to be one that i was going to buy. This product did not disapoint. The artwork is beautiful and top notch. Each of the grffin species is unique and a pleasure to read about as well as being a creative take on different griffin species. I also thought it was a very nice touch that the authorsand artist included pictures of heraldic griffins as a base for the griffins species that they used. You also getinformation on how to take care of the young griffins, an cavalier order and 2 archtypes to round out the PDF as a very nice addtion. The only thing that might turn people away is the price. $6.95 is not a great amount but for some this might be too much for a PDF that some might consider to be fairly short. My advice in regards to this product is to go for it. if you love griffins you will love this product. I do. if the authors and artist decide to do other prodcuts like this with other creatures (and i hope they do), I would like to make a few suggestions. First; if it is possible to have the wonderful artwork on a single page alone and then follow with the stats. Second: two of the enteries have double page artwork which in this PDF, means that i am looking at half of the picture at a time. I feel like i am missing the full effect of the artwork when i have to look at the picutres only a half at a time. Perhapes having a PDF that has a double page style would be better for those pages. Despite those two little things (and they are very little in my opinion), i love this product. I do hope that the authors make more. My suggestions, phoenix, unicorn and pegasus but i would love to see any entry in this new series. Great job and i look forward to more releases like this. FIVE stars :)
