well first, good news, you have a good sense for general look of the page and screentone :D
how ever you could do with another denoiser. I suggest topaz labs, get the denoise and clean programs :P get them here or pirate them XD
http://www.topazlabs.com/You pages however are well leveled, and even though you didnt use the ideal program for denoising i know you used it pretty darn well :P
here's a guide for a topaz-based technique ^^
http://ieatsoul.com/training-ground/cleaning-101/what you do need it to level just a bit more cus you have blotches here and there and your pages are sometimes blurry :P also there are some spots that are left unburned. and there's a gutter you need to crop out on most pages. Here you go for those
