First of all, congrats on being funded already. Well deserved seeing the artwork of your portraits cards.
A few thoughts though:
1. the back design should be clearly visible in the campaign. If I didn't overlook something there is no picture of it at all and you can only have a short glimpse of it in the trailer and the picture where it is covered from the tuck box render.
2. While the artwork is superb on itself, I wish it would be playing card art.
What I mean by that is - not taking anything away from the beautiful art itself - but there is something that makes a deck of playing cards exceptional compared to just art printed on tiny pasteboards. Things like a two-way back designs and two-way courts for example. Would be awesome to have this combined with your art skill. Maybe we'll see a V3 of this deck
3. Who prints the cards? Some collectors are interested in print and stock quality and the producing company is as important as the artwork to them. It should be mentioned where the cards are going to be printed.
