Hi, Babalon. I wanted to weigh in here, as I think your new deck is coming out phenomenally well, and while I totally understand how something like "artistic fatigue" can set in for various reasons, I have no trouble saying that if we can assume the rest of the deck will come out as well as these first half-dozen cards, I will be ordering one!
Some general thoughts:
I think your artwork is really growing visibly, even since the Rosetta. Maybe it's the fact that you're now working on a larger scale and then reducing the images, as opposed to just creating them at card-size, or maybe you've just learned a lot and really honed your skills, but these images look even more sharp and accomplished to me, without sacrificing any of the terrific color work that I think was such a big part of why people were drawn to the Rosetta. I also like the modern vibe in most of the cards that updates them without crushing their traditional meanings, and I love the innovations you're lavishing upon each of them -- it's fantastic that you're not just falling back on tried and true images here ("Okay, Emperor...guy on a throne, maybe ram horns, check...next!").
Some specifics.
I love the new Hierophant. This card and the Emperor are probably my least favorites overall in many decks and just on the conceptual level (I think I may have a quiet dislike for male authority figures...), but so far, both cards in this series are very, very appealing to me, and especially the Hierophant. I get a sort of "Wisdom is the key that unlocks doors" vibe from the image, and I also feel that the pillars create a link with the High Priestess card -- I know that such a link is appropriate, but as I was first learning Tarot, it took me way longer to get that those two cards are connected than it took me to grasp the Empress/Emperor connection, which always seems more overt.
Speaking of, I like this Empress -- she feels more modern than usual to me, although I'm not sure exactly which elements make me say that (it's not as obvious as in, say, the Magus card...). When I first saw this Empress, I, too, mistakenly thought I was looking at a shield in the lower left, but I almost immediately understood what was going on. I guess maybe adding the Venus symbol to the smaller version of the shot would help to keep people from failing to see what the blow-up in the corner represents...? And I personally don't mind that the Empress and Emperor aren't more alike, or that all of the characters aren't the same sizes in their cards as each other.
I do think -- and this is an observation more than a criticism, as I don't believe you've ever stated your intent on this point -- the level of "modern-ness" kind of fluctuates from one card to the next. The Fool and the Magus have very modernizing elements, the Empress and the Emperor seem somewhat modern to me, and the High Priestess and the Hierophant are a lot more timeless to me than the others, without any clear modern elements. None of this is to say this is "bad" or "wrong," either...I'm just saying that after the Fool and the Magus, I think I was prepared to play spot-the-modern-reference in every card, but maybe that was never your intent, which is more than cool. My own assumptions are my problem...
Anyway, I think the deck is beautiful so far, and having just looked at the cards again, I'm even going to say that pound for pound, I think the Hierophant is my favorite of the bunch to date -- and I
never say that about a deck! So...just one individual's opinion, but I think it's really excellent work so far, and I'd be on board to snap this up if you keep going!
