OK, a few things:
Collector, maybe it's just my browser or the computer I'm using at work right now, but your first post's link back to your blog is broken. It generates a "page not found" error.
I just found the error - the date portion of the URL after wordpress.com should read "/2013/04/26/" and not "/2013/03/06/" - OR - you should remove the "-is-updated" portion of the link, depending on which page you're trying to point us to.
I've seen this deck before, and I liked it. But I know that at HOPC, there's two things going on.
1) They have a LOT of submissions. Many of them are crap, but enough of them are high-caliber that their production calendar is set for months.
2) If either Alex or Kevin personally don't like the work, for whatever reasons, it stands a low chance of HOPC making it. It stands to reason - it's their show.
She'd stand a much better chance of getting this made on a KS project than through HOPC. Optionally, she should shop it around to the other card design houses - they've been known to take interest in new artists before. Last time I looked, Ellusionist is still holding in the wings a project they worked on with Alex Chin, designer of the Seasons decks - the running rumor is that it's a special Seasons release for E. Could be the summer and winter decks, or it could be something completely different - I don't know. Dan and Dave expressed interest in other artists' work before, a prime example being the Tungstene deck they eventually carried and sold out of. The worst thing that will happen is they say no and she can run over to KS and make her own project rather than being another company's hired gun.
I personally think the work is great and would love to see this deck on pasteboards sometime soon. Is she based in one of KS's "no-fly zone" countries? EDIT: just checked, she's from Orlando according to her Behance profile. She'd be free to launch this on KS herself if she was interested.
