David Day's A TOLKIEN BESTIARY is a scholarly, definitive and enchantingly beautiful explanation of all the imaginary beasts, monsters, races, nations,deities, fauna and flora of J.R.R- Tolkien's fantasy worlds of Middle-earth and the Undying Lands.
David Day has identified, analyzed and described 129 separate races. Each is lucidly explained in terms of its physical appearance, language, behavior and culture. A TOLKIEN BESTIARY does not retell their stories: its purpose is to make Tolkien’s own books more accessible by identifying his living creatures and explaining their roles in his epic world.
If you're talking of the angle dragon seen on this image, then I must say that's definitely not unpolished IMO and I love it. I definitely prefer this over the generic dragons we get on book covers.
I wasn't saying it as a bad thing, just saying it looks a lot more raw and unfiltered than your standard DND sourcebook.
I guess it's just a different style.
