I agree with the comparison between this deck and the Vargo--this one has more color, detail, and variety. The parallel I see is in the generation of the deck by an artist with an independent body of work that is strongly informing the design choices over Tarot design structure.
For the Five of Skulls, I can see some of the meaning carried forward from the RWS system, though more from Waite's book than his deck. Thoth and Golden Dawn emphasize the financial/work/material aspect of the suit more than does Daniels' design, which appears to be focusing on the reversed (or most negative) suite of meanings from Waite/Mathers/Ettailla: LOVE AS BAD AS IT GETS
You can see the Golden Dawn astrological symbols of Mercury in Taurus on the gravestone. This could also be a depiction of a Ghoul with a freshly obtained corpse.
From Waite's Pictorial Key:
Divinatory Meanings: The card foretells material trouble above all, whether in the form illustrated--that is, destitution--or otherwise. For some cartomancists, it is a card of love and lovers-wife, husband, friend, mistress; also concordance, affinities. These alternatives cannot be harmonized. Reversed: Disorder, chaos, ruin, discord, profligacy.
Mathers (one of Waite's sources):
73. Five of Pentacles.--Lover or Mistress, Love, Sweetness, Affection, Pure and Chaste Love; R. Disgraceful Love, Imprudence, License, Profligacy.
Etteilla (another of Waite's sources, and you can see where the "harmonization" issue comes from)
ETTEILLA: Lover, Person In Love, Chivalrous Man [Galant], Refined Woman [Galante], Husband, Wife, Spouse, Friend.— Paramour, Mistress.—Love, Cherish, Adore.—Harmony, Accord, Suitable Character, Presentable, Decorum.
Reversed: Muddled, Disorganization.—Debauchery, Disorder, Trouble, Confusion, Chaos.—Damage, Ravage, Ruin.—Dissipation, Wasting [Consomption, therefore also Tuberculosis?].—Dissoluteness, Licentiousness.—Discord, Disharmony, Conflict.
Waite as Theriens (quoting himself, oh that guy!)
TRADITION
Lover, mistress, also husband and wife, friend, beloved person. Accord, convenience, well-being, affinity. Reversed they give: Bad conduct, ruin even, confusion, disorder, discord, dissipation, chaos, profligacy. Mr. W. says: "It foretells material trouble above all."
THEORY
The latter saying of Mr. W. is probably correct in any case, but we do not agree that the different renderings "cannot be harmonised." The Fire of the heart on the Ninth house, that of Sagittarius, explains them all without difficulty. It is the emanation of love, which makes practically the lover and the mistress, e.g. husband and wife, when regularised by civil law, and friends, when between persons of the same sex, sympathy and popularity, enthusiasm, hopefulness, love of travelling, roaming about, which in weaker cases easily leads to Bohemian habits, carelessness, disorder and so on. Society will call this in many cases bad conduct, and find much to criticise. That the expansive nature indicated by this card causes 'material troubles above all,' is evident, because it means that more is given out than received, which in matters of this material world does in fact bring troubles. But of a sort that may be easily forgiven, and helped, if not carried too far.
CONCLUSION
Emanation, expansion, love-making and the consequences: lover, mistress, husband, wife, friend; sympathy, popularity, enthusiasm, hopefulness, well-being, affinity. Expenses, material troubles, and in weak cases: disorder, vagrancy, roaming about without aim, waywardness, bad conduct, profligacy, confusion, etc. It is sure to indicate love outside the lines of a legal marriage. Strong individualism, which however is probably ruled by a strong will and a good heart. Brilliancy, but sometimes lack of the sense of responsibility. Travelling or emigration will do much good.
