Emily - it's really difficult to say whether it's Thoth or RWS based. I can't see a reference in the LWB anywhere and a card like, say, 8 Cups seems to me to have the Thoth feel, others - for example 9 Swords - are very RWS.
Baba-Prague - I can't say I'd really thought about the Hierophant except to notice that for me this is a really "different" interpretation. I guess you could put the Devil in the same category as he appears to be about to step onto the chest of the naked woman at the bottom of the card, but isn't that a fairly "normal" sort of depiction for this card? There's an obviously distraught naked woman cowering under the 5 Swords and a similarly positioned one in the 10 Wands is about to have a rock dropped on her from on high, but I think that's about it. I must admit I just love the style of the artwork and so I can't say I feel uncomfortable with them at all. If you want to see some of the other cards, PM me with your e-mail address and I'll scan a few in for you.
Astril - sounds like you've really "clicked" with your deck. It would be lovely to be able to read with it, but as I said earlier I'm not confident I'll be able to proceed that far. It's certainly impressed a couple of my very picky Tarot friends at work who've been known to turn their noses up at quite a few decks so far.
