Aw you :3! The splash is it's not officially out yet to be fair there which is why it's taking a while...
The rear illustration is is because I like showing the non main cast too, it's a thing I do sometimes especially when I love the designs of the characters (and I totally do for KyoAni)!
So it's girls design over boys design? Not that Oreki would mind being all that small in the background, but Satoshi certainly would have some cheecky comment on being left out. =P
(Do you happen to be one Mayaka-Fan? Kind is suspicious she's out there on both sides. *cough*)
Fear not, we're planning a book with Part 2, takes time to plan that kind of thing though as I have a LOT of material to work from here so stay tuned on that frontier

.
Now I have a LOT of water in my mouth right now and hope a LOT of this LOT of material will make it in LOTs into part 2~ Wonder how thick the book can be, given the second box doesn't appear to be all that much thicker than the first, given the space placeholder. (Putting my thumbs up that it will be thicker than the You lie in April one.) Incidentally, don't know if you are allowed to say anything about it. But do you have access to other artwork material apart from the Japanese home releases? There are a couple of other illustrations I like, which are
seriously hard to track down. Among them is one poster artwork and the only thing that exists for it on the internet is some halfway high resolution photograph of it. I haven't even ever seen it on yahoo auctions. ,_,
(Kind of doubt it's possible, if if it were, it'll totally make my day. Wouldn't mind a Terror in Resonance-ish artbook either even with the unhandy oversize, but that's probably not happening.)
On another note:
After all the Hyouka explosion in my head, that Utena announcement just started to sink in. I have the Nozomi one pre-ordered right now and 50-50% undecided whether to cancel it or not. Like really 50-50 of total undecisiveness and it makes me dizzy. Any hints on whatever front that there are to possibly tip the balance over to whichever side? =P
