thanks for the reply and your feedback, really appreciate. Im gonna take this in account and try to rework them.
But its true, its more of a contemporary version than and Antic one.
And again, the whole deck should be black and gold, its was just not possible to achieve that with the prototypes.
I'm in agreement in that it's a basically nice design, but there's not a lot here to really make this design stand out above the herd. It looks very modern, while "alchemy" to me can mentally evoke something more ancient. There's nothing wrong with a modern design, per se, but you really want to make this deck something special - what isn't already out there? What can you bring to this deck that no one else has? What direction can you take this design that has never been done before?
Everyone remembers the name of the first team to reach the summit at Mount Everest. Few people will remember the second team, or the third. Absolutely no one remembers the 8,426th team. So if you're planning to climb Everest and you aren't the first, you'd better bring something unique to your attempt if you want it to be remembered - and if you're planning to make a modern deck of cards and you aren't the first (trust me, you're far from it), how can you it do better than anyone else before you?
BTW: if you want to see a REALLY special modern deck that better evoke "alchemy" than your design? Look for Sentinels by Theory11, printed by USPC. That design was modern and ancient all at the same time, and it absolutely rocked. Use that for inspiration, but go in a DIFFERENT direction, somewhere no one else has, if you really want to grab eyeballs and raise dollars.
