Because this is a rate my comic book "pics" I'll say it looks like you bumped up the contrast and saturation on them. They look just a little too bright and unnatural to me :)

Yea I did...
 

Yea I post processed them in PS. I guess I dont really care about grading values with the "Rate my books" request. Just the books themselves and the collection in general, also the photographic style of the images. I see your point though as far as the over PS editing. Im a digital photographer and graphic designer so I have a tendency to over do stuff....... THanks....
