I realize what was meant by a carousel going in circles. But its a touch of personal style whimsy and fantasy, which I believe most readers can deal with, besides, not all journeys have a specific beginning or end do they, either by time or destination. Any given delivered message may not be the final say or absolute conclusion. This journey which might be interpreted as continuing or returning, might (I emphasize might) provide an additional dimension to the card.
As for the gender. Just because the Rider has been mostly depicted as a male in the past doesn't mean it has to remain so. Surely in the context of a reading a message might be delivered or recieved in a number of ways and from a variety of sources. Traditional symbology is one thing, but it has to be appreciated in context. In a historical perspective of the times I'm sure a male rider may have been an appropriate and obvious visual metaphor. But to continue using it when designing a contemporary deck seems to be tradition for the sake of tradition, repeating what was done before just because thats how its "supposed" to be. Conceptually it would be quite relevant in this day and age to show the message deliverer as either gender. My USPS person is a female, my Fedex is a male. For that matter one might also utilize a "You've got mail" graphic icon of some kind to depict e-mail etc etc. Past verses present depictions are a common dilemma and balancing act when designing decks, both Tarot and apparently also Lenormand. Similarly, clothing is a obvious indicator of historical time, place and social status. Less clothing or the full monty is timeless and neutral.
I personally have no interest in simply producing a comfortably similar deck to the hundreds that already exist. What would be the point? So there are several cards where the changes might be too much, but I'm ok with that. I realize that in veering off the path, the results will not sit well with some readers and this deck will not be for them. I respect that too.
