Awesome. I'd be willing to pay quite a bit for a full book of this if it was edition neutral (no stat blocks etc.) and had some ecology added.
No stat blocks? That's like buying a player's handbook just for the descriptions of the powers, with no levels or damage included. It's got to have the stats because seeing a cool monster you can play is a lot cooler than just seeing some fictional monster. Forexample, I'd rather see a stat block saying what Dr. Octopus' arms do on a full attack than just see a picture of him and a little description of how he can use them as a backscratcher or a sewer snake.
I know you're not thinking of doing loads more, but might I urge some enterprising 3rd party to leap upon this idea and get to work? A great way of adding usefullness to 3e monsters!
