My Lupin set also came today and for the most part I thought the release was superb. Great job folks.
Still, one aspect I wasn't as taken with was the slightly mottled effect on the art book. I'm assuming this is a stylistic choice similar to the Eureka 7 release and not some off batch of paper; after all the book is designed to look like an old note file, complete with fake hole punch marks. It's a cool concept and all, and I'd definitely appreciate it on the cover, opening glossaries, edges of the pages, etc. However, I would prefer it didn't bleed over and interfere with the actual art itself, particularly the light sketches and line art. It's a little distracting when viewing the images.
For all I know this could be part of the original Japanese presentation, at which point there's little to be done, but if not I feel it's probably worth mentioning for future consideration. Again, I'm not really disappointed or annoyed and I definitely don't want to curtail the design choices of the staff, as I've really enjoyed many of the inventive choices of recent titles; this set included. However, I'd personally suggest they were toned back a fraction in future so that a line of separation exists between the stylistic presentation & the illustrations themselves. I'm not sure if I'm on my own on this but I thought it was worth throwing it out as feedback.
