Simon, I've been going thru the book from cover to cover. Nice work! and great ideas...
If there's another reprint, I hope they can correct the photo reproductions; that's a detractor to the book.
If you send me all the originals I'll spend an hour in Photoshop and send them back 
Evil Genius has this problem with other products too, so it's probably totally on their pre-press end, not you!
Getting good 'Product Shots' is non-trivial and takes a lot of work and lighting setup etc.
...you don't LOOK Evil.
