Finally got to see what it looks like (can't see a lot of free image hosts at school) and... very nice. Only thing I think you could possibly do to enhance it all is to try burning a corner or two and maybe add some page creases to add the finishing touches to the old fashioned look.
Great tutorial nonetheless.
EDIT: Congrats on the Recommended Tutorial. Are these the only two that you've done for the GIMP? I wanna make sure the index is right.
Observative.. I assume you mean? I get PR for people's resources, either via buying (using forum points/money), by swapping posting rights (my resources for theirs - only for PR though), or by people being great and just allowing me to do so for free. =)
