The book is too small. I had the same problem with Monsters of The Id. Great book, but too small. A lot of effort going into something like this. Make it 48 or 64 pages.
Page of monster counters is an excellent idea.
For the black & white portion, I'd say just go with stat blocks. Either standard Monster Manual or abbreviated.
Of course the real question I have is this coming out under the Malhavok Banner? Will it see print at a latter date?
Will the monsters have racial stats ala MM 3.5? Tactics? What levels are these aimed at?
Price range? I ask price range because while the b & w part is 'free', it's going to have some effect on the overall price of the material.
