This is a nice light set of fantasy RPG rules, using just 2d6 and some scratch paper.
The rules give you four classes and some advanced classes (think D&D prestige classes), combat and magic rules, and about a dozen critters in a bestiary. Appendices give you advice on making your own classes and monsters.
Characters have no attributes or skills, and are defined solely by their classes. There are no lists of equipment, or rules for travel and such.
At $1.00 for 21 pages Witches and Wyverns is a decent value, though limited. An experienced GM could easily use it as to run hours worth of adventures with little to no prep, and making up new content for the game would be simple.
Other stuff: To my eyes the layout looks fine. I didn't see any major typographical errors. The art is minimal but there is some art.
