Oh wow that fully naked Valeera art! Stunning!
I disagree that Feral Rage needs to be restricted to the guro version. Yeah, the girl's copping some nasty scratches on her tit and punctures to her neck, but the point of guro is the MURDER aspect of it, as well as the extreme mutilation. This is more like (very) rough sex. I'll admit it's borderline though. If she was in more visible agony, I'd agree that it'd need to go.
I was a bit surprised when I saw you'd swapped the art for Holy Champion to Hooded Acolyte, but I can't argue it fits better.
Blood to Ichor is a bit on the borderline guro side too- it doesn't feature a gruesome murder, but it's definitely sexualised torture. Might have been better to leave that one unchanged, actually, because the art doesn't really fit the theme of the card.
I was looking back over the old arts as well and found the new arts for Power Word: Shield, Arcane Shot, Drakonid Crusher, Avenging Wrath, Aldor Peacekeeper and Demonfire. You also brought the old Arcane Intellect art back as the new Arcane Explosion and found new (and better) art for Savage Roar and Succubus. Nicely done! I love the way you're always trying to improve on what you've already done rather than exclusively focusing on the new stuff. Not sure why you changed Onyxia's art to the old Succubus art, though.
Thanks for your work as always. I don't think I'd be able to stand Hearthstone without it.
